| CVE-2023-3609 | 3 Debian, Linux, Redhat | 9 Debian Linux, Linux Kernel, Enterprise Linux and 6 more | 2024-08-02 | 7.8 High |
| A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability. We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc. | ||||
| CVE-2023-3610 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2024-08-02 | 7.8 High |
| A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795. | ||||
| CVE-2023-3446 | 2 Openssl, Redhat | 5 Openssl, Enterprise Linux, Jboss Core Services and 2 more | 2024-08-02 | 5.3 Medium |
| Issue summary: Checking excessively long DH keys or parameters may be very slow. Impact summary: Applications that use the functions DH_check(), DH_check_ex() or EVP_PKEY_param_check() to check a DH key or DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. The function DH_check() performs various checks on DH parameters. One of those checks confirms that the modulus ('p' parameter) is not too large. Trying to use a very large modulus is slow and OpenSSL will not normally use a modulus which is over 10,000 bits in length. However the DH_check() function checks numerous aspects of the key or parameters that have been supplied. Some of those checks use the supplied modulus value even if it has already been found to be too large. An application that calls DH_check() and supplies a key or parameters obtained from an untrusted source could be vulernable to a Denial of Service attack. The function DH_check() is itself called by a number of other OpenSSL functions. An application calling any of those other functions may similarly be affected. The other functions affected by this are DH_check_ex() and EVP_PKEY_param_check(). Also vulnerable are the OpenSSL dhparam and pkeyparam command line applications when using the '-check' option. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue. | ||||
| CVE-2023-3358 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2024-08-02 | 5.5 Medium |
| A null pointer dereference was found in the Linux kernel's Integrated Sensor Hub (ISH) driver. This issue could allow a local user to crash the system. | ||||
| CVE-2023-3417 | 3 Debian, Mozilla, Redhat | 7 Debian Linux, Thunderbird, Enterprise Linux and 4 more | 2024-08-02 | 7.5 High |
| Thunderbird allowed the Text Direction Override Unicode Character in filenames. An email attachment could be incorrectly shown as being a document file, while in fact it was an executable file. Newer versions of Thunderbird will strip the character and show the correct file extension. This vulnerability affects Thunderbird < 115.0.1 and Thunderbird < 102.13.1. | ||||
| CVE-2023-3390 | 3 Linux, Netapp, Redhat | 12 Linux Kernel, H300s, H410c and 9 more | 2024-08-02 | 7.8 High |
| A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97. | ||||
| CVE-2023-3338 | 4 Debian, Linux, Netapp and 1 more | 4 Debian Linux, Linux Kernel, Active Iq Unified Manager and 1 more | 2024-08-02 | 6.5 Medium |
| A null pointer dereference flaw was found in the Linux kernel's DECnet networking protocol. This issue could allow a remote user to crash the system. | ||||
| CVE-2023-3341 | 4 Debian, Fedoraproject, Isc and 1 more | 8 Debian Linux, Fedora, Bind and 5 more | 2024-08-02 | 7.5 High |
| The code that processes control channel messages sent to `named` calls certain functions recursively during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack memory, causing `named` to terminate unexpectedly. Since each incoming control channel message is fully parsed before its contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key; only network access to the control channel's configured TCP port is necessary. This issue affects BIND 9 versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18, 9.19.0 through 9.19.16, 9.9.3-S1 through 9.16.43-S1, and 9.18.0-S1 through 9.18.18-S1. | ||||
| CVE-2023-3316 | 2 Libtiff, Redhat | 2 Libtiff, Enterprise Linux | 2024-08-02 | 5.9 Medium |
| A NULL pointer dereference in TIFFClose() is caused by a failure to open an output file (non-existent path or a path that requires permissions like /dev/null) while specifying zones. | ||||
| CVE-2023-3355 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2024-08-02 | 4.7 Medium |
| A NULL pointer dereference flaw was found in the Linux kernel's drivers/gpu/drm/msm/msm_gem_submit.c code in the submit_lookup_cmds function, which fails because it lacks a check of the return value of kmalloc(). This issue allows a local user to crash the system. | ||||
| CVE-2023-3354 | 3 Fedoraproject, Qemu, Redhat | 10 Fedora, Qemu, Advanced Virtualization and 7 more | 2024-08-02 | 7.5 High |
| A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service. | ||||
| CVE-2023-3269 | 3 Fedoraproject, Linux, Redhat | 3 Fedora, Linux Kernel, Enterprise Linux | 2024-08-02 | 7.8 High |
| A vulnerability exists in the memory management subsystem of the Linux kernel. The lock handling for accessing and updating virtual memory areas (VMAs) is incorrect, leading to use-after-free problems. This issue can be successfully exploited to execute arbitrary kernel code, escalate containers, and gain root privileges. | ||||
| CVE-2023-3247 | 2 Php, Redhat | 2 Php, Enterprise Linux | 2024-08-02 | 2.6 Low |
| In PHP versions 8.0.* before 8.0.29, 8.1.* before 8.1.20, 8.2.* before 8.2.7 when using SOAP HTTP Digest Authentication, random value generator was not checked for failure, and was using narrower range of values than it should have. In case of random generator failure, it could lead to a disclosure of 31 bits of uninitialized memory from the client to the server, and it also made easier to a malicious server to guess the client's nonce. | ||||
| CVE-2023-3268 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2024-08-02 | 7.1 High |
| An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel internal information. | ||||
| CVE-2023-3301 | 2 Qemu, Redhat | 4 Qemu, Advanced Virtualization, Enterprise Linux and 1 more | 2024-08-02 | 5.6 Medium |
| A flaw was found in QEMU. The async nature of hot-unplug enables a race scenario where the net device backend is cleared before the virtio-net pci frontend has been unplugged. A malicious guest could use this time window to trigger an assertion and cause a denial of service. | ||||
| CVE-2023-3212 | 5 Debian, Fedoraproject, Linux and 2 more | 14 Debian Linux, Fedora, Linux Kernel and 11 more | 2024-08-02 | 4.4 Medium |
| A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic. | ||||
| CVE-2023-3171 | 1 Redhat | 2 Enterprise Linux, Jboss Enterprise Application Platform | 2024-08-02 | 7.5 High |
| A flaw was found in EAP-7 during deserialization of certain classes, which permits instantiation of HashMap and HashTable with no checks on resources consumed. This issue could allow an attacker to submit malicious requests using these classes, which could eventually exhaust the heap and result in a Denial of Service. | ||||
| CVE-2023-3164 | 2 Libtiff, Redhat | 2 Libtiff, Enterprise Linux | 2024-08-02 | 5.5 Medium |
| A heap-buffer-overflow vulnerability was found in LibTIFF, in extractImageSection() at tools/tiffcrop.c:7916 and tools/tiffcrop.c:7801. This flaw allows attackers to cause a denial of service via a crafted tiff file. | ||||
| CVE-2023-3223 | 1 Redhat | 20 Enterprise Linux, Integration, Jboss Data Grid and 17 more | 2024-08-02 | 7.5 High |
| A flaw was found in undertow. Servlets annotated with @MultipartConfig may cause an OutOfMemoryError due to large multipart content. This may allow unauthorized users to cause remote Denial of Service (DoS) attack. If the server uses fileSizeThreshold to limit the file size, it's possible to bypass the limit by setting the file name in the request to null. | ||||
| CVE-2023-3141 | 4 Debian, Linux, Netapp and 1 more | 6 Debian Linux, Linux Kernel, Hci Baseboard Management Controller and 3 more | 2024-08-02 | 7.1 High |
