| CVE-2024-28834 | gnutls28 | 3.6.13-2ubuntu1.10 | A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce size from 513 to 512 bits, exposing a potential timing side-channel. |
| CVE-2024-2961 | glibc | 2.31-0ubuntu9.14 | The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable. |
| CVE-2024-2236 | libgcrypt20 | 1.8.5-5ubuntu1.1 | A timing-based side-channel flaw was found in libgcrypt's RSA implementation. This issue may allow a remote attacker to initiate a Bleichenbacher-style attack, which can lead to the decryption of RSA ciphertexts. |
| CVE-2024-28182 | nghttp2 | 1.40.0-1ubuntu0.2 | nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2 v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream. There is no workaround for this vulnerability. |
| CVE-2024-26461 | krb5 | 1.17-6ubuntu4.4 | Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/lib/gssapi/krb5/k5sealv3.c. |
| CVE-2024-26458 | krb5 | 1.17-6ubuntu4.4 | Kerberos 5 (aka krb5) 1.21.2 contains a memory leak in /krb5/src/lib/rpc/pmap_rmt.c. |
| CVE-2024-26462 | krb5 | 1.17-6ubuntu4.4 | Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/kdc/ndr.c. |
| CVE-2024-28085 | util-linux | 2.34-0.1ubuntu9.4 | wall in util-linux through 2.40, often installed with setgid tty permissions, allows escape sequences to be sent to other users' terminals through argv. (Specifically, escape sequences received from stdin are blocked, but escape sequences received from argv are not blocked.) There may be plausible scenarios where this leads to account takeover. |
| CVE-2020-22916 | xz-utils | 5.2.4-1ubuntu1.1 | ** DISPUTED ** An issue discovered in XZ 5.2.5 allows attackers to cause a denial of service via decompression of a crafted file. NOTE: the vendor disputes the claims of "endless output" and "denial of service" because decompression of the 17,486 bytes always results in 114,881,179 bytes, which is often a reasonable size increase. |
| CVE | Package | Version | Description |

| CVE-2023-26604 | systemd | 245.4-4ubuntu3.23 | systemd before 247 does not adequately block local privilege escalation for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output. |
| CVE-2023-7008 | systemd | 245.4-4ubuntu3.23 | A vulnerability was found in systemd-resolved. This issue may allow systemd-resolved to accept records of DNSSEC-signed domains even when they have no signature, allowing man-in-the-middles (or the upstream DNS resolver) to manipulate records. |
| CVE-2022-3219 | gnupg2 | 2.2.19-3ubuntu2.2 | GnuPG can be made to spin on a relatively small input by (for example) crafting a public key with thousands of signatures attached, compressed down to just a few KB. |
| CVE-2023-50495 | ncurses | 6.2-0ubuntu2.1 | NCurse v6.4-20230418 was discovered to contain a segmentation fault via the component _nc_wrap_entry(). |
| CVE-2023-45918 | ncurses | 6.2-0ubuntu2.1 | ncurses 6.4-20230610 has a NULL pointer dereference in tgetstr in tinfo/lib_termcap.c. |
| CVE-2016-2781 | coreutils | 8.30-3ubuntu2 | chroot in GNU coreutils, when used with --userspec, allows local users to escape to the parent session via a crafted TIOCSTI ioctl call, which pushes characters to the terminal's input buffer. |
| CVE-2023-29383 | shadow | 1:4.8.1-1ubuntu5.20.04.5 | In Shadow 4.13, it is possible to inject control characters into fields provided to the SUID program chfn (change finger). Although it is not possible to exploit this directly (e.g., adding a new user fails because \n is in the block list), it is possible to misrepresent the /etc/passwd file when viewed. Use of \r manipulations and Unicode characters to work around blocking of the : character make it possible to give the impression that a new user has been added. In other words, an adversary may be able to convince a system administrator to take the system offline (an indirect, social-engineered denial of service) by demonstrating that "cat /etc/passwd" shows a rogue user account. |
| CVE-2013-4235 | shadow | 1:4.8.1-1ubuntu5.20.04.5 | shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees |
| CVE | Package | Version | Description |
|---|---|---|---|
| CVE-2016-20013 | glibc | 2.31-0ubuntu9.14 | sha256crypt and sha512crypt through 0.6 allow attackers to cause a denial of service (CPU consumption) because the algorithm's runtime is proportional to the square of the length of the password. |
| CVE-2017-11164 | pcre3 | 2:8.39-12ubuntu0.1 | In PCRE 8.41, the OP_KETRMAX feature in the match function in pcre_exec.c allows stack exhaustion (uncontrolled recursion) when processing a crafted regular expression. |
