CVE-2020-27827 5 Fedoraproject, Lldpd Project, Openvswitch and 2 more 28 Fedora, Lldpd, Openvswitch and 25 more 2024-11-21 7.5 High
A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-27824 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-11-21 5.5 Medium
A flaw was found in OpenJPEG’s encoder in the opj_dwt_calc_explicit_stepsizes() function. This flaw allows an attacker who can supply crafted input to decomposition levels to cause a buffer overflow. The highest threat from this vulnerability is to system availability.
CVE-2020-27823 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-11-21 7.8 High

CVE-2020-27820 4 Fedoraproject, Linux, Oracle and 1 more 6 Fedora, Linux Kernel, Communications Cloud Native Core Binding Support Function and 3 more 2024-11-21 4.7 Medium
A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could happen if removing device (that is not common to remove video card physically without power-off, but same happens if "unbind" the driver).
CVE-2020-27783 6 Debian, Fedoraproject, Lxml and 3 more 9 Debian Linux, Fedora, Lxml and 6 more 2024-11-21 6.1 Medium
A XSS vulnerability was discovered in python-lxml's clean module. The module's parser didn't properly imitate browsers, which caused different behaviors between the sanitizer and the user's page. A remote attacker could exploit this flaw to run arbitrary HTML/JS code.
CVE-2020-27781 2 Fedoraproject, Redhat 6 Fedora, Ceph, Ceph Storage and 3 more 2024-11-21 7.1 High
User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting in potential privilege escalation. An Open Stack Manila user can request access to a share to an arbitrary cephx user, including existing users. The access key is retrieved via the interface drivers. Then, all users of the requesting OpenStack project can view the access key. This enables the attacker to target any resource that the user has access to. This can be done to even "admin" users, compromising the ceph administrator. This flaw affects Ceph versions prior to 14.2.16, 15.x prior to 15.2.8, and 16.x prior to 16.2.0.
CVE-2020-27779 4 Fedoraproject, Gnu, Netapp and 1 more 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more 2024-11-21 7.5 High
A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent SecureBoot protections after proper triage about grub's memory layout. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-27769 3 Fedoraproject, Imagemagick, Redhat 3 Fedora, Imagemagick, Enterprise Linux Desktop 2024-11-21 3.3 Low
In ImageMagick versions before 7.0.9-0, there are outside the range of representable values of type 'float' at MagickCore/quantize.c.
CVE-2020-27749 4 Fedoraproject, Gnu, Netapp and 1 more 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more 2024-11-21 6.7 Medium
A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage, without sufficient bounds checking. If the function is called with a command line that references a variable with a sufficiently large payload, it is possible to overflow the stack buffer, corrupt the stack frame and control execution which could also circumvent Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-27619 4 Fedoraproject, Oracle, Python and 1 more 5 Fedora, Communications Cloud Native Core Network Function Cloud Native Environment, Python and 2 more 2024-11-21 9.8 Critical
In Python 3 through 3.9.0, the Lib/test/multibytecodec_support.py CJK codec tests call eval() on content retrieved via HTTP.
CVE-2020-27170 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2024-11-21 4.7 Medium
An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This affects pointer types that do not define a ptr_limit.
CVE-2020-26572 4 Debian, Fedoraproject, Opensc Project and 1 more 4 Debian Linux, Fedora, Opensc and 1 more 2024-11-21 5.5 Medium
The TCOS smart card software driver in OpenSC before 0.21.0-rc1 has a stack-based buffer overflow in tcos_decipher.
CVE-2020-26571 4 Debian, Fedoraproject, Opensc Project and 1 more 4 Debian Linux, Fedora, Opensc and 1 more 2024-11-21 5.5 Medium
The gemsafe GPK smart card software driver in OpenSC before 0.21.0-rc1 has a stack-based buffer overflow in sc_pkcs15emu_gemsafeGPK_init.
CVE-2020-26570 4 Debian, Fedoraproject, Opensc Project and 1 more 4 Debian Linux, Fedora, Opensc and 1 more 2024-11-21 5.5 Medium

CVE-2020-26558 6 Bluetooth, Debian, Fedoraproject and 3 more 35 Bluetooth Core Specification, Debian Linux, Fedora and 32 more 2024-11-21 4.2 Medium
Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time.
CVE-2020-26555 4 Bluetooth, Fedoraproject, Intel and 1 more 33 Bluetooth Core Specification, Fedora, Ac 3165 and 30 more 2024-11-21 5.4 Medium
Bluetooth legacy BR/EDR PIN code pairing in Bluetooth Core Specification 1.0B through 5.2 may permit an unauthenticated nearby device to spoof the BD_ADDR of the peer device to complete pairing without knowledge of the PIN.
CVE-2020-26154 5 Debian, Fedoraproject, Libproxy Project and 2 more 6 Debian Linux, Fedora, Libproxy and 3 more 2024-11-21 9.8 Critical
url.cpp in libproxy through 0.4.15 is prone to a buffer overflow when PAC is enabled, as demonstrated by a large PAC file that is delivered without a Content-length header.
CVE-2020-26116 8 Canonical, Debian, Fedoraproject and 5 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2024-11-21 7.2 High
http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of HTTPConnection.request.
CVE-2020-25719 5 Canonical, Debian, Fedoraproject and 2 more 18 Ubuntu Linux, Debian Linux, Fedora and 15 more 2024-11-21 7.2 High
A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise.
CVE-2020-25717 5 Canonical, Debian, Fedoraproject and 2 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2024-11-21 8.1 High
A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.
