Gentoo Linux Security Advisory

Title: Pango: Buffer overflow (GLSA 201909-03)
Severity: normal
Exploitable: remote
Date: 2019-09-06
Bug(s): #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: x11-libs/pango
Vulnerable: < 1.42.4-r2
Unaffected: >= 1.42.4-r2
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=x11-libs/pango-1.42.4-r2"
