https://notcve.org/view.php?id=CVE-2023-52355
An out-of-memory flaw was found in libtiff that could be triggered by passing a crafted tiff file to the TIFFRasterScanlineSize64() API. This flaw allows a remote attacker to cause a denial of service via a crafted input with a size smaller than 379 KB. Se encontró un fallo de falta de memoria en libtiff que podría activarse al pasar un archivo tiff diseñado a la API TIFFRasterScanlineSize64(). Este fallo permite que un atacante remoto provoque una denegación de servicio a través de una entrada manipulada con un tamaño inferior a 379 KB. • https://access.redhat.com/security/cve/CVE-2023-52355 https://bugzilla.redhat.com/show_bug.cgi?id=2251326 https://gitlab.com/libtiff/libtiff/-/issues/621 • CWE-787: Out-of-bounds Write •
CVSS: 8.3EPSS: 0%CPEs: 4EXPL: 0CVE-2023-40547 – Shim: rce in http boot support may lead to secure boot bypass
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.

A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This flaw allows a local user to cause an information leak problem while freeing the old quota file names before a potential failure, leading to a use-after-free. Se encontró una falla de use-after-free en __ext4_remount en fs/ext4/super.c en ext4 en el kernel de Linux.

CVSS: 6.6EPSS: 0%CPEs: 5EXPL: 0CVE-2024-0607 – Kernel: nf_tables: pointer math issue in nft_byteorder_eval()
https://notcve.org/view.php?id=CVE-2024-0607
A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality. • https://access.redhat.com/security/cve/CVE-2024-0607 https://bugzilla.redhat.com/show_bug.cgi?id=2258635 https://github.com/torvalds/linux/commit/c301f0981fdd3fd1ffac6836b423c4d7a8e0eb63 https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html • CWE-229: Improper Handling of Values •

https://notcve.org/view.php?id=CVE-2024-0646
An out-of-bounds memory write flaw was found in the Linux kernel’s Transport Layer Security functionality in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user to crash or potentially escalate their privileges on the system.
