Debian DSA-5202-1 : unzip - security update

medium Nessus Plugin ID 163926

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-5202 advisory.

 Sandipan Roy discovered two vulnerabilities in InfoZIP's unzip program, a de-archiver for .zip files, which could result in denial of service or potentially the execution of arbitrary code. For the stable distribution (bullseye), these problems have been fixed in version 6.0-26+deb11u1. We recommend that you upgrade your unzip packages. For the detailed security status of unzip please refer to its security tracker page at: https://security-tracker.debian.org/tracker/unzip

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

Solution

Upgrade the unzip packages.

For the stable distribution (bullseye), these problems have been fixed in version 6.0-26+deb11u1.
