| 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. | ||||
| CVE-2020-13753 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-11-21 | 10.0 Critical |
| The bubblewrap sandbox of WebKitGTK and WPE WebKit, prior to 2.28.3, failed to properly block access to CLONE_NEWUSER and the TIOCSTI ioctl. CLONE_NEWUSER could potentially be used to confuse xdg-desktop-portal, which allows access outside the sandbox. TIOCSTI can be used to directly execute commands outside the sandbox by writing to the controlling terminal's input buffer, similar to CVE-2017-5226. | ||||
| CVE-2020-13696 | 5 Canonical, Debian, Fedoraproject and 2 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-11-21 | 4.4 Medium |
| An issue was discovered in LinuxTV xawtv before 3.107. The function dev_open() in v4l-conf.c does not perform sufficient checks to prevent an unprivileged caller of the program from opening unintended filesystem paths. This allows a local attacker with access to the v4l-conf setuid-root program to test for the existence of arbitrary files and to trigger an open on arbitrary files with mode O_RDWR. To achieve this, relative path components need to be added to the device path, as demonstrated by a v4l-conf -c /dev/../root/.bash_history command. | ||||
| CVE-2020-13659 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-11-21 | 2.5 Low |
| address_space_map in exec.c in QEMU 4.2.0 can trigger a NULL pointer dereference related to BounceBuffer. | ||||
| CVE-2020-13645 | 5 Broadcom, Canonical, Fedoraproject and 2 more | 6 Fabric Operating System, Ubuntu Linux, Fedora and 3 more | 2024-11-21 | 6.5 Medium |
| In GNOME glib-networking through 2.64.2, the implementation of GTlsClientConnection skips hostname verification of the server's TLS certificate if the application fails to specify the expected server identity. This is in contrast to its intended documented behavior, to fail the certificate verification. Applications that fail to provide the server identity, including Balsa before 2.5.11 and 2.6.x before 2.6.1, accept a TLS certificate if the certificate is valid for any host. | ||||
