Severity:normal
Title:Pango: Buffer overflow
Date:09/06/2019
Bugs: #692110
ID:201909-03

Synopsis

A buffer overflow in Pango might allow an attacker to execute arbitrary code.

Background

Pango is a library for layout and rendering of internationalized text.

Affected packages

Package Vulnerable Unaffected Architecture(s)
x11-libs/pango < 1.42.4-r2 >= 1.42.4-r2 All supported architectures

Description

A buffer overflow has been discovered in Pango’s pango_log2vis_get_embedding_levels function.

Impact

A remote attacker could entice a user to process a specially crafted string with functions like pango_itemize, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All Pango users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=x11-libs/pango-1.42.4-r2"
