Mandriva Linux Security Advisory : fetchmail (MDVSA-2010:037)

This script is Copyright (C) 2010-2015 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

A vulnerability have been discovered and corrected in fetchmail :

The sdump function in sdump.c in fetchmail 6.3.11, 6.3.12, and 6.3.13,
when running in verbose mode on platforms for which char is signed,
allows remote attackers to cause a denial of service (application
crash) or possibly execute arbitrary code via an SSL X.509 certificate
containing non-printable characters with the high bit set, which
triggers a heap-based buffer overflow during escaping (CVE-2010-0562).

This update provides fetchmail 6.3.14, which is not vulnerable to this
issue.
