| 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. |
| 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-2023-0464 | openssl | 1.1.1f-1ubuntu2.17 | A security vulnerability has been identified in all supported versions of OpenSSL related to the verification of X.509 certificate chains that include policy constraints. Attackers may be able to exploit this vulnerability by creating a malicious certificate chain that triggers exponential use of computational resources, leading to a denial-of-service (DoS) attack on affected systems. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function. |
| CVE-2023-0465 | openssl | 1.1.1f-1ubuntu2.17 | Applications that use a non-default option when verifying certificates may be vulnerable to an attack from a malicious CA to circumvent certain checks. Invalid certificate policies in leaf certificates are silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A malicious CA could use this to deliberately assert invalid certificate policies in order to circumvent policy checking on the certificate altogether. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function. |
| 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-2023-24593 | glib2.0 | 2.64.6-1~ubuntu20.04.4 | glib: DoS caused by handling a malicious text-form variant |
| CVE-2023-25180 | glib2.0 | 2.64.6-1~ubuntu20.04.4 | glib: DoS caused by malicious serialised variant |
| 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-2018-10126 | tiff | 4.1.0+git191117-2ubuntu0.20.04.8 | LibTIFF 4.0.9 has a NULL pointer dereference in the jpeg_fdct_16x16 function in jfdctint.c. |
| CVE-2023-25193 | harfbuzz | 2.6.4-1ubuntu4.2 | hb-ot-layout-gsubgpos.hh in HarfBuzz through 6.0.0 allows attackers to trigger O(n^2) growth via consecutive marks during the process of looking back for base glyphs when attaching marks. |
| CVE-2017-7475 | cairo | 1.16.0-4ubuntu1 | Cairo version 1.15.4 is vulnerable to a NULL pointer dereference related to the FT_Load_Glyph and FT_Render_Glyph resulting in an application crash. |
| CVE-2018-18064 | cairo | 1.16.0-4ubuntu1 | cairo through 1.15.14 has an out-of-bounds stack-memory write during processing of a crafted document by WebKitGTK+ because of the interaction between cairo-rectangular-scan-converter.c (the generate and render_rows functions) and cairo-image-compositor.c (the _cairo_image_spans_and_zero function). |
| CVE-2019-6461 | cairo | 1.16.0-4ubuntu1 | An issue was discovered in cairo 1.16.0. There is an assertion problem in the function _cairo_arc_in_direction in the file cairo-arc.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. |
