Echo: 7zip: security update to 25.01+dfsg-1~deb13u2

medium Tenable Cloud Security Plugin ID 457689

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 7-Zip for Windows through 26.01 fails to preserve the Mark-of-the-Web when extracting a crafted RAR5
 archive, because its guard that suppresses an archive-supplied Zone.Identifier stream matches the exact
 name 'Zone.Identifier' while a RAR5 STM record named ':Zone.Identifier:$DATA' is not matched and NTFS
 canonicalizes it to the same stream, overwriting the propagated Internet-zone marker with ZoneId=0. A
 second STM record named '::$DATA' overwrites the extracted file's default data stream, letting an attacker
 defeat SmartScreen/MotW warnings and spoof file content. (CVE-2026-58052)

Solution

Update the 7zip library and its related packages to version 25.01+dfsg-1~deb13u2 or later.
