libproxy: User-assisted execution of arbitrary code

libproxy: User-assisted execution of arbitrary code A buffer overflow in libproxy might allow remote attackers to execute arbitrary code. libproxy 2014-04-07 2014-04-07 438146 remote 0.4.10 0.4.10

libproxy is a library for automatic proxy configuration management.

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

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.

There is no known workaround at this time.

All libproxy users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-libs/libproxy-0.4.10"
