| 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-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-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-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-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-2018-10126 | tiff | 4.1.0+git191117-2ubuntu0.20.04.11 | LibTIFF 4.0.9 has a NULL pointer dereference in the jpeg_fdct_16x16 function in jfdctint.c. |
| CVE-2023-3164 | tiff | 4.1.0+git191117-2ubuntu0.20.04.11 | A heap-buffer-overflow vulnerability was found in LibTIFF, in extractImageSection() at tools/tiffcrop.c:7916 and tools/tiffcrop.c:7801. This flaw allows attackers to cause a denial of service via a crafted tiff file. |
| CVE-2023-6228 | tiff | 4.1.0+git191117-2ubuntu0.20.04.11 | An issue was found in the tiffcp utility distributed by the libtiff package where a crafted TIFF file on processing may cause a heap-based buffer overflow leads to an application crash. |
| CVE-2023-6277 | tiff | 4.1.0+git191117-2ubuntu0.20.04.11 | An out-of-memory flaw was found in libtiff. Passing a crafted tiff file to TIFFOpen() API may allow a remote attacker to cause a denial of service via a craft input with size smaller than 379 KB. |
| 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-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-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 | 1:4.8.1-1ubuntu5.20.04.4 | 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-2023-4641 | shadow | 1:4.8.1-1ubuntu5.20.04.4 | A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. This may allow an attacker with enough access to retrieve the password from the memory. |
