| 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-2023-1916 | tiff | 4.1.0+git191117-2ubuntu0.20.04.8 | A flaw was found in tiffcrop, a program distributed by the libtiff package. A specially crafted tiff file can lead to an out-of-bounds read in the extractImageSection function in tools/tiffcrop.c, resulting in a denial of service and limited information disclosure. This issue affects libtiff versions 4.x. |
| 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-2023-26965 | tiff | 4.1.0+git191117-2ubuntu0.20.04.8 | loadImage() in tools/tiffcrop.c in LibTIFF through 4.5.0 has a heap-based use after free via a crafted TIFF image. |
| CVE-2023-3316 | tiff | 4.1.0+git191117-2ubuntu0.20.04.8 | A NULL pointer dereference in TIFFClose() is caused by a failure to open an output file (non-existent path or a path that requires permissions like /dev/null) while specifying zones. |
| 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. |
| 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-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-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-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-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. |
