There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow. Se presenta un problema en grub2 versiones anteriores a 2.06, en la función read_section_as_string(). Se espera que el nombre de la fuente sea una longitud máxima UINT32_MAX - 1 en bytes, pero no lo verifica antes de proceder con la asignación del búfer para leer el valor desde el valor de la fuente. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00016.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00017.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-14310 https://security.gentoo.org/glsa/202104-05 https://usn.ubuntu.com/4432-1 https://access.redhat.com/security/cve/CVE-2020-14310 https://bugzilla.redhat.com/show_bug.cgi?id=1852030 • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •

A memory corruption issue was found in Artifex Ghostscript 9.50 and 9.52. Use of a non-standard PostScript operator can allow overriding of file access controls. The 'rsearch' calculation for the 'post' size resulted in a size that was too large, and could underflow to max uint32_t. This was fixed in commit 5d499272b95a6b890a1397e11d20937de000d31b.

In FreeRDP less than or equal to 2.1.2, an integer overflow exists due to missing input sanitation in rdpegfx channel. All FreeRDP clients are affected. The input rectangles from the server are not checked against local surface coordinates and blindly accepted. A malicious server can send data that will crash the client later on (invalid length arguments to a `memcpy`) This has been fixed in 2.2.0. As a workaround, stop using command line arguments /gfx, /gfx-h264 and /network:auto En FreeRDP versiones anteriores o igual a 2.1.2, se presenta un desbordamiento de enteros debido a una falta de saneamiento de entrada en el canal rdpegfx. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00010.html https://github.com/FreeRDP/FreeRDP/blob/616af2d5b86dc24c7b3e89870dbcffd841d9a535/ChangeLog#L4 https://github.com/FreeRDP/FreeRDP/pull/6382 https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-4r38-6hq7-j3j9 https://lists.debian.org/debian-lts-announce/2023/10/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6Y35HBHG2INICLSGCIKNAR7GCXEHQACQ https://lists.fedoraproject.org/archives/list&#x • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow •
