1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
net-im/pidgin	< 2.10.6	>= 2.10.6	All supported architectures

Related bugreports: #425076

A buffer overflow in Pidgin might allow remote attackers to execute arbitrary code or cause Denial of Service.

2. Impact Information

Pidgin is a GTK Instant Messenger client for a variety of instant messaging protocols. libpurple is the core library for Pidgin.

A stack-based buffer overflow vulnerability has been found in the MXit protocol plug-in for libpurple.

A remote attacker could possibly execute arbitrary code with the privileges of the Pidgin process, or cause a Denial of Service condition.

3. Resolution Information

There is no known workaround at this time.

All Pidgin users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-im/pidgin-2.10.6"
