Debian DSA-5413-1 : sniproxy - security update

critical Nessus Plugin ID 176431

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 host has a package installed that is affected by a vulnerability as referenced in the dsa-5413 advisory.

An issue has been found in sniproxy, a transparent TLS and HTTP layer 4 proxy with SNI support. Due to bad handling of wildcard backend hosts, a crafted HTTP or TLS packet might lead to remote arbitrary code execution. For the stable distribution (bullseye), this problem has been fixed in version 0.6.0-2+deb11u1.
We recommend that you upgrade your sniproxy packages. For the detailed security status of sniproxy please refer to its security tracker page at: https://security-tracker.debian.org/tracker/sniproxy

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

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

Solution

Upgrade the sniproxy packages.

For the stable distribution (bullseye), this problem has been fixed in version 0.6.0-2+deb11u1.
