| 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-2022-41409 | pcre2 | 10.34-7ubuntu0.1 | Integer overflow vulnerability in pcre2test before 10.41 allows attackers to cause a denial of service or other unspecified impacts via negative input. |
| 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-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-2024-26461 | krb5 | 1.17-6ubuntu4.7 | Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/lib/gssapi/krb5/k5sealv3.c. |
| 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-2023-26604 | systemd | 245.4-4ubuntu3.24 | 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 | 245.4-4ubuntu3.24 | 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. |
