Detail

Synopsis

A buffer overflow in libproxy might allow remote attackers to execute arbitrary code.

Background

libproxy is a library for automatic proxy configuration management.

Description

A boundary error when processing the proxy.pac file could cause a stack-based buffer overflow.

Impact

A man-in-the-middle attacker could provide a specially crafted proxy.pac file on a remote server, 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 libproxy users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/libproxy-0.4.10"
