Detail
| The Red Hat Security Response Team discovered that libproxy, a library for automatic proxy configuration management, applied insufficient validation to the Content-Length header sent by a server providing a proxy.pac file. Such remote server could trigger an integer overflow and consequently overflow an in-memory buffer. For the stable distribution (squeeze), this problem has been fixed in version 0.3.1-2+squeeze1. For the testing distribution (wheezy), and the unstable distribution (sid), this problem has been fixed in version 0.3.1-5.1. We recommend that you upgrade your libproxy packages. |
