Echo: 7zip: security update to 22.01+really26.01+dfsg-0+deb12u1

medium Tenable Self-Hosted Container Security Plugin ID 461071

Description

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

 - 7-Zip is a file archiver with a high compression ratio. Versions 9.18 through 26.00 contain a heap out-of-
 bounds read in 7-Zip Ar handler BSD SYMDEF parser. A 4-byte heap out-of-bounds read exists in the Unix ar
 archive parser in 7-Zip. When parsing a BSD-style __.SYMDEF symbol table, the ParseLibSymbols function
 reads a 32-bit namesSize field via Get32 at a position that can equal the buffer size, reading 4 bytes
 past the end of the heap allocation. This reads uninitialized heap data under the default allocator.
 Version 26.01 patches the issue. (CVE-2026-48112)

Solution

Update the 7zip library and its related packages to version 22.01+really26.01+dfsg-0+deb12u1 or later.
