Package : p7zip Version : 16.02+really25.01+dfsg-0+deb11u1 CVE ID : CVE-2022-47069 CVE-2023-31102 CVE-2023-40481 CVE-2023-52168 CVE-2023-52169 CVE-2024-11612 CVE-2025-11001 CVE-2025-11002 CVE-2025-53817 CVE-2025-55188 Debian Bug : 1111068

Multiple vulnerabilities were discovered in p7zip, a now unmaintained fork of 7-Zip, a file archiver handling multiple formats.

To address these security vulnerabilities, whose fixes are unfortunately not isolated, this update replaces p7zip with 7-Zip v25 (which now supports GNU/Linux natively), slightly modified to make it reasonably compatible with p7zip.

CVE-2022-47069

heap-buffer-overflow vulnerability via the function NArchive::NZip::CInArchive::FindCd

CVE-2023-31102

Ppmd7.c allows an integer underflow and invalid read operation via a crafted 7Z archive.

CVE-2023-40481

SquashFS File Parsing Out-Of-Bounds Write RCE

CVE-2023-52168

heap-based buffer overflow in NTFS handler

CVE-2023-52169

CVE-2024-11612

CVE-2025-11001

CVE-2025-53817
