CVE-2020-14346 | 3 Canonical, Redhat, X.org | 3 Ubuntu Linux, Enterprise Linux, Xorg-server | 2024-11-21 | 7.8 High |
A flaw was found in xorg-x11-server before 1.20.9. An integer underflow in the X input extension protocol decoding in the X server may lead to arbitrary access of memory contents. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2020-14345 | 3 Canonical, Redhat, X.org | 3 Ubuntu Linux, Enterprise Linux, X Server | 2024-11-21 | 7.8 High |
A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Out-Of-Bounds access in XkbSetNames function may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2020-14344 | 5 Canonical, Fedoraproject, Opensuse and 2 more | 5 Ubuntu Linux, Fedora, Leap and 2 more | 2024-11-21 | 6.7 Medium |
An integer overflow leading to a heap-buffer overflow was found in The X Input Method (XIM) client was implemented in libX11 before version 1.6.10. As per upstream this is security relevant when setuid programs call XIM client functions while running with elevated privileges. No such programs are shipped with Red Hat Enterprise Linux. | ||||
CVE-2020-14314 | 5 Canonical, Debian, Linux and 2 more | 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more | 2024-11-21 | 5.5 Medium |
A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash the system if the directory exists. The highest threat from this vulnerability is to system availability. | ||||
CVE-2020-14311 | 4 Canonical, Gnu, Opensuse and 1 more | 11 Ubuntu Linux, Grub2, Leap and 8 more | 2024-11-21 | 5.7 Medium |
There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow. | ||||
CVE-2020-14310 | 4 Canonical, Gnu, Opensuse and 1 more | 11 Ubuntu Linux, Grub2, Leap and 8 more | 2024-11-21 | 5.7 Medium |
There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow. | ||||
CVE-2020-14303 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-11-21 | 7.5 High |
A flaw was found in the AD DC NBT server in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4. A samba user could send an empty UDP packet to cause the samba server to crash. | ||||
CVE-2020-14154 | 2 Canonical, Mutt | 2 Ubuntu Linux, Mutt | 2024-11-21 | 4.8 Medium |
Mutt before 1.14.3 proceeds with a connection even if, in response to a GnuTLS certificate prompt, the user rejects an expired intermediate certificate. | ||||
CVE-2020-14093 | 4 Canonical, Debian, Mutt and 1 more | 4 Ubuntu Linux, Debian Linux, Mutt and 1 more | 2024-11-21 | 5.9 Medium |
Mutt before 1.14.3 allows an IMAP fcc/postpone man-in-the-middle attack via a PREAUTH response. | ||||
CVE-2020-14001 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2024-11-21 | 9.8 Critical |
The kramdown gem before 2.3.0 for Ruby processes the template option inside Kramdown documents by default, which allows unintended read access (such as template="/etc/passwd") or unintended embedded Ruby code execution (such as a string that begins with template="string://<%= `). NOTE: kramdown is used in Jekyll, GitLab Pages, GitHub Pages, and Thredded Forum. | ||||
CVE-2020-13974 | 4 Canonical, Debian, Linux and 1 more | 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more | 2024-11-21 | 7.8 High |
An issue was discovered in the Linux kernel 4.4 through 5.7.1. drivers/tty/vt/keyboard.c has an integer overflow if k_ascii is called several times in a row, aka CID-b86dab054059. NOTE: Members in the community argue that the integer overflow does not lead to a security issue in this case. | ||||
CVE-2020-13935 | 8 Apache, Canonical, Debian and 5 more | 23 Tomcat, Ubuntu Linux, Debian Linux and 20 more | 2024-11-21 | 7.5 High |
The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service. | ||||
CVE-2020-13934 | 7 Apache, Canonical, Debian and 4 more | 17 Tomcat, Ubuntu Linux, Debian Linux and 14 more | 2024-11-21 | 7.5 High |
An h2c direct connection to Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M5 to 9.0.36 and 8.5.1 to 8.5.56 did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service. | ||||
CVE-2020-13904 | 3 Canonical, Debian, Ffmpeg | 3 Ubuntu Linux, Debian Linux, Ffmpeg | 2024-11-21 | 5.5 Medium |
FFmpeg 2.8 and 4.2.3 has a use-after-free via a crafted EXTINF duration in an m3u8 file because parse_playlist in libavformat/hls.c frees a pointer, and later that pointer is accessed in av_probe_input_format3 in libavformat/format.c. | ||||
CVE-2020-13881 | 4 Arista, Canonical, Debian and 1 more | 4 Cloudvision Portal, Ubuntu Linux, Debian Linux and 1 more | 2024-11-21 | 7.5 High |
In support.c in pam_tacplus 1.3.8 through 1.5.1, the TACACS+ shared secret gets logged via syslog if the DEBUG loglevel and journald are used. | ||||
CVE-2020-13800 | 3 Canonical, Opensuse, Qemu | 3 Ubuntu Linux, Leap, Qemu | 2024-11-21 | 6.0 Medium |
ati-vga in hw/display/ati.c in QEMU 4.2.0 allows guest OS users to trigger infinite recursion via a crafted mm_index value during an ati_mm_read or ati_mm_write call. | ||||
CVE-2020-13777 | 5 Canonical, Debian, Fedoraproject and 2 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-11-21 | 7.4 High |
GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket (a loss of confidentiality in TLS 1.2, and an authentication bypass in TLS 1.3). The earliest affected version is 3.6.4 (2018-09-24) because of an error in a 2018-09-18 commit. Until the first key rotation, the TLS server always uses wrong data in place of an encryption key derived from an application. | ||||
CVE-2020-13765 | 4 Canonical, Debian, Qemu and 1 more | 4 Ubuntu Linux, Debian Linux, Qemu and 1 more | 2024-11-21 | 5.6 Medium |
rom_copy() in hw/core/loader.c in QEMU 4.0 and 4.1.0 does not validate the relationship between two addresses, which allows attackers to trigger an invalid memory copy operation. | ||||
CVE-2020-13757 | 4 Canonical, Fedoraproject, Python-rsa Project and 1 more | 4 Ubuntu Linux, Fedora, Python-rsa and 1 more | 2024-11-21 | 7.5 High |
Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior (such as by causing excessive memory allocation). | ||||
CVE-2020-13754 | 4 Canonical, Debian, Qemu and 1 more | 5 Ubuntu Linux, Debian Linux, Qemu and 2 more | 2024-11-21 | 6.7 Medium |
hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address in an msi-x mmio operation. |
