Astra Linux – Vulnerability in grub2

A crafted 16-bit grayscale PNG image may lead to an out-of-bounds write in the heap area. An attacker may exploit this to cause heap data corruption or, ultimately, arbitrary code execution and circumvent secure boot protections. This issue is highly complex to exploit; an attacker needs to perfo...

Astra Linux – Vulnerability in openexr

A flaw was discovered in the function dataWindowForTile of the IlmImf/ImfTiledMisc.cpp file. An attacker who can submit a crafted file for processing with OpenEXR could trigger an integer overflow, resulting in an out-of-bounds write operation on the heap. The most significant impact of this flaw...

Astra Linux – Vulnerability in TIF format

A flaw was discovered in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations...

CVE-2026-68767 hashcat through 7.1.2 Off-by-One Out-of-Bounds Heap Write in fgetl()

hashcat's fgetl function in src/filehandling.c writes a null terminator one byte past the caller's buffer when an input line is exactly the buffer length. Attackers can trigger this out-of-bounds heap write by providing a hash file, potfile, or wordlist containing a line of exactly HCBUFSIZLARGE...

CVE-2026-68767

hashcat through 7.1.2 contains an off-by-one out-of-bounds heap write in the fgetl() function (src/filehandling.c). When an input line is exactly HCBUFSIZ_LARGE bytes long, the function writes a null terminator one byte past the caller's buffer. An attacker can trigger this by supplying a crafted...

EUVD-2026-64167

LibVNCClient is a library for easy implementation of a VNC client. In versions 0.9.12 through 0.9.15, a malicious or man-in-the-middle VNC server can force a connecting libvncclient to write attacker-controlled data past the end of its framebuffer. This is an out-of-bounds heap write with...
