7-Zip < 25.00

medium Nessus Plugin ID 242639

Synopsis

The remote host is missing a security update.

Description

The version of 7-Zip installed on the remote host is prior to 25.00. It is, therefore, affected by multiple vulnerabilies:

 - An error in Z-zip's RAR5 handler's error correction for corrupted items can lead to a buffer overflow, resulting in memory corruption and denial of service.
 (CVE-2025-53816)

 - A Null pointer dereference in 7-Zip's implimentation of the Compound handler can lead to denial of service at specific values. (CVE-2025-53817)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to 7-Zip version 25.00 or later.
