libsoup: Arbitrary remote code execution

Background

libsoup is an HTTP client/server library for GNOME.

Description

A stack based buffer overflow vulnerability was discovered in libsoup.

Impact

A remote attacker, by using specially crafted HTTP requests, could execute arbitrary code with the privileges of the process.

Workaround

There is no known workaround at this time.

Resolution

All libsoup users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-libs/libsoup-2.56.1"

Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
