CVE-2026-14191

An out-of-bounds heap write exists in the RAR5 recovery-volume .rev parser in WinRAR and UnRAR RecVolumes5::ReadHeader in recvol5.cpp. The RecItems vector is sized only when the first .rev file in a set is processed; subsequent .rev files supply an independent RecNum value that is validated again...

CVE-2026-14191

CVE-2026-14191 describes an out-of-bounds heap write in WinRAR/UnRAR’s RAR5 recovery-volume (.rev) parser (RecVolumes5::ReadHeader). The RecItems vector is sized based on the first .rev file; subsequent .rev files supply an independent RecNum that is validated against that file’s TotalCount but n...

CVE-2026-58049

FFmpeg's RASC video decoder decodedlta in libavcodec/rasc.c performs 32-bit reads and writes at the row cursor before the NEXTLINE row-boundary check and validates the DLTA region in pixel rather than byte units, so a DLTA run on a PAL8 frame can access several bytes past the row allocation. A...

CVE-2026-58049

CVE-2026-58049 concerns FFmpeg’s RASC video decoder (decode_dlta in libavcodec/rasc.c). The issue arises when the code performs 32-bit reads/writes at the row cursor before the NEXT_LINE boundary check and validates the DLTA region in pixels rather than bytes. On PAL8 frames, this enables a DLTA ...

DEBIAN-CVE-2026-56123

socat versions 1.8.0.0 through 1.8.1.1 contain a heap-based buffer overflow vulnerability that allows a malicious SOCKS5 proxy server to overwrite adjacent heap memory by exploiting a sign-extension flaw in the DOMAINNAME reply parser. During connection setup, the domain name length byte is read...

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 imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Versions of ImageMagick below 14.8.2 include insecure functions: SeekBlob, which allows advancing the stream offset beyond the current end without increasing capacity, and WriteBlob, which expands the...

Astra Linux – Vulnerability in Cpio

In GNU Cpio from version 2.13 onwards, attackers can execute arbitrary code by using a crafted pattern file. This occurs due to a dstring.c dsfgetstr integer overflow, which triggers an out-of-bounds heap write. NOTE: It is unclear whether there are common cases where the pattern file, associated...

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...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the htundoimpl function when decoding a specially crafted HTJ2K-compressed EXR file. An attacker can cause a heap out-of-bounds write by supplying a file with a large decode-channelsi.width value that...
