CVE-2023-1637 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-11-21 | 5.5 Medium |
A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of the CPU similar to the speculative execution behavior kind of attacks. | ||||
CVE-2023-1393 | 3 Fedoraproject, Redhat, X.org | 7 Fedora, Enterprise Linux, Rhel Aus and 4 more | 2024-11-21 | 7.8 High |
A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later. | ||||
CVE-2023-1390 | 2 Linux, Redhat | 5 Linux Kernel, Enterprise Linux, Rhel Aus and 2 more | 2024-11-21 | 7.5 High |
A remote denial of service vulnerability was found in the Linux kernel’s TIPC kernel module. The while loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue. Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system to instantly spike to 100%, causing a denial of service condition. | ||||
CVE-2023-1281 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-11-21 | 7.8 High |
Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. | ||||
CVE-2023-1192 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-11-21 | 6.5 Medium |
A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service. | ||||
CVE-2023-1095 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-11-21 | 5.5 Medium |
In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list -- the list head is all zeroes, this results in a NULL pointer dereference. | ||||
CVE-2023-0767 | 2 Mozilla, Redhat | 10 Firefox, Firefox Esr, Thunderbird and 7 more | 2024-11-21 | 8.8 High |
An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory writes via PKCS 12 Safe Bag attributes being mishandled. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8. | ||||
CVE-2023-0616 | 2 Mozilla, Redhat | 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more | 2024-11-21 | 6.5 Medium |
If a MIME email combines OpenPGP and OpenPGP MIME data in a certain way Thunderbird repeatedly attempts to process and display the message, which could cause Thunderbird's user interface to lock up and no longer respond to the user's actions. An attacker could send a crafted message with this structure to attempt a DoS attack. This vulnerability affects Thunderbird < 102.8. | ||||
CVE-2023-0547 | 2 Mozilla, Redhat | 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more | 2024-11-21 | 6.5 Medium |
OCSP revocation status of recipient certificates was not checked when sending S/Mime encrypted email, and revoked certificates would be accepted. Thunderbird versions from 68 to 102.9.1 were affected by this bug. This vulnerability affects Thunderbird < 102.10. | ||||
CVE-2023-0494 | 3 Fedoraproject, Redhat, X.org | 22 Fedora, Enterprise Linux, Enterprise Linux Aus and 19 more | 2024-11-21 | 7.8 High |
A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions. | ||||
CVE-2023-0461 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-11-21 | 7.8 High |
There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is created from the listener, the context is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c | ||||
CVE-2023-0430 | 2 Mozilla, Redhat | 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more | 2024-11-21 | 6.5 Medium |
Certificate OCSP revocation status was not checked when verifying S/Mime signatures. Mail signed with a revoked certificate would be displayed as having a valid signature. Thunderbird versions from 68 to 102.7.0 were affected by this bug. This vulnerability affects Thunderbird < 102.7.1. | ||||
CVE-2023-0286 | 3 Openssl, Redhat, Stormshield | 13 Openssl, Enterprise Linux, Jboss Core Services and 10 more | 2024-11-21 | 7.4 High |
There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or enact a denial of service. In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network. | ||||
CVE-2023-0266 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-11-21 | 7.9 High |
A use after free vulnerability exists in the ALSA PCM package in the Linux Kernel. SNDRV_CTL_IOCTL_ELEM_{READ|WRITE}32 is missing locks that can be used in a use-after-free that can result in a priviledge escalation to gain ring0 access from the system user. We recommend upgrading past commit 56b88b50565cd8b946a2d00b0c83927b7ebb055e | ||||
CVE-2022-4883 | 2 Redhat, X.org | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2024-11-21 | 8.8 High |
A flaw was found in libXpm. When processing files with .Z or .gz extensions, the library calls external programs to compress and uncompress files, relying on the PATH environment variable to find these programs, which could allow a malicious user to execute other programs by manipulating the PATH environment variable. | ||||
CVE-2022-4378 | 2 Linux, Redhat | 9 Linux Kernel, Enterprise Linux, Rhel Aus and 6 more | 2024-11-21 | 7.8 High |
A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system. | ||||
CVE-2022-4254 | 2 Fedoraproject, Redhat | 16 Sssd, Enterprise Linux, Enterprise Linux Desktop and 13 more | 2024-11-21 | 8.8 High |
sssd: libsss_certmap fails to sanitise certificate data used in LDAP filters | ||||
CVE-2022-48829 | 1 Redhat | 3 Rhel Aus, Rhel E4s, Rhel Tus | 2024-11-21 | 5.5 Medium |
In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix NFSv3 SETATTR/CREATE's handling of large file sizes iattr::ia_size is a loff_t, so these NFSv3 procedures must be careful to deal with incoming client size values that are larger than s64_max without corrupting the value. Silently capping the value results in storing a different value than the client passed in which is unexpected behavior, so remove the min_t() check in decode_sattr3(). Note that RFC 1813 permits only the WRITE procedure to return NFS3ERR_FBIG. We believe that NFSv3 reference implementations also return NFS3ERR_FBIG when ia_size is too large. | ||||
CVE-2022-48828 | 1 Redhat | 3 Rhel Aus, Rhel E4s, Rhel Tus | 2024-11-21 | 5.5 Medium |
In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix ia_size underflow iattr::ia_size is a loff_t, which is a signed 64-bit type. NFSv3 and NFSv4 both define file size as an unsigned 64-bit type. Thus there is a range of valid file size values an NFS client can send that is already larger than Linux can handle. Currently decode_fattr4() dumps a full u64 value into ia_size. If that value happens to be larger than S64_MAX, then ia_size underflows. I'm about to fix up the NFSv3 behavior as well, so let's catch the underflow in the common code path: nfsd_setattr(). | ||||
CVE-2022-48827 | 1 Redhat | 3 Rhel Aus, Rhel E4s, Rhel Tus | 2024-11-21 | 5.5 Medium |
In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix the behavior of READ near OFFSET_MAX Dan Aloni reports: > Due to commit 8cfb9015280d ("NFS: Always provide aligned buffers to > the RPC read layers") on the client, a read of 0xfff is aligned up > to server rsize of 0x1000. > > As a result, in a test where the server has a file of size > 0x7fffffffffffffff, and the client tries to read from the offset > 0x7ffffffffffff000, the read causes loff_t overflow in the server > and it returns an NFS code of EINVAL to the client. The client as > a result indefinitely retries the request. The Linux NFS client does not handle NFS?ERR_INVAL, even though all NFS specifications permit servers to return that status code for a READ. Instead of NFS?ERR_INVAL, have out-of-range READ requests succeed and return a short result. Set the EOF flag in the result to prevent the client from retrying the READ request. This behavior appears to be consistent with Solaris NFS servers. Note that NFSv3 and NFSv4 use u64 offset values on the wire. These must be converted to loff_t internally before use -- an implicit type cast is not adequate for this purpose. Otherwise VFS checks against sb->s_maxbytes do not work properly. |
