https://notcve.org/view.php?id=CVE-2023-52356
A segment fault (SEGV) flaw was found in libtiff that could be triggered by passing a crafted tiff file to the TIFFReadRGBATileExt() API. This flaw allows a remote attacker to cause a heap-buffer overflow, leading to a denial of service. Se encontró un fallo de falla de segmento (SEGV) en libtiff que podría activarse al pasar un archivo tiff diseñado a la API TIFFReadRGBATileExt(). Este fallo permite que un atacante remoto provoque un desbordamiento de búfer en la región Heap de la memoria, lo que lleva a una denegación de servicio. • https://access.redhat.com/security/cve/CVE-2023-52356 https://bugzilla.redhat.com/show_bug.cgi?id=2251344 https://gitlab.com/libtiff/libtiff/-/issues/622 https://gitlab.com/libtiff/libtiff/-/merge_requests/546 https://lists.debian.org/debian-lts-announce/2024/03/msg00011.html https://access.redhat.com/errata/RHSA-2024:5079 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-40547
A remote code execution vulnerability was found in Shim. The Shim boot support trusts attacker-controlled values when parsing an HTTP response. This flaw allows an attacker to craft a specific malicious HTTP request, leading to a completely controlled out-of-bounds write primitive and complete system compromise. This flaw is only exploitable during the early boot phase, an attacker needs to perform a Man-in-the-Middle or compromise the boot server to be able to exploit this vulnerability successfully.
