| CVE-2023-26604 | systemd | 245.4-4ubuntu3.22 | 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-2016-2568 | policykit-1 | 0.105-26ubuntu1.3 | pkexec, when used with --user nonpriv, 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-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-2023-28322 | curl | 7.68.0-1ubuntu2.18 | An information disclosure vulnerability exists in curl |
| CVE-2023-28321 | curl | 7.68.0-1ubuntu2.18 | An improper certificate validation vulnerability exists in curl |
| CVE-2023-34969 | dbus | 1.12.16-2ubuntu2.3 | D-Bus before 1.15.6 sometimes allows unprivileged users to crash dbus-daemon. If a privileged user with control over the dbus-daemon is using the org.freedesktop.DBus.Monitoring interface to monitor message bus traffic, then an unprivileged user with the ability to connect to the same dbus-daemon can cause a dbus-daemon crash under some circumstances via an unreplyable message. When done on the well-known system bus, this is a denial-of-service vulnerability. The fixed versions are 1.12.28, 1.14.8, and 1.15.6. |
| CVE-2022-3857 | libpng1.6 | 1.6.37-2 | A flaw was found in libpng 1.6.38. A crafted PNG image can lead to a segmentation fault and denial of service in png_setup_paeth_row() function. |
| CVE-2023-2953 | openldap | 2.4.49+dfsg-2ubuntu1.9 | A vulnerability was found in openldap. This security flaw causes a null pointer dereference in ber_memalloc_x() function. |
| CVE-2021-28861 | python3.8 | 3.8.10-0ubuntu1~20.04.8 | ** DISPUTED ** Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is disputed by a third party because the http.server.html documentation page states "Warning: http.server is not recommended for production. It only implements basic security checks." |
| 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-2013-4235 | shadow | 1:4.8.1-1ubuntu5.20.04.4 | shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees |
| CVE-2023-29383 | shadow | 1:4.8.1-1ubuntu5.20.04.4 | 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-2023-26604 | systemd | 245.4-4ubuntu3.21 | 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. |
