Detail
| Problem Description: Updated libproxy packages that fix one security issue are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: libproxy is a library that handles all the details of proxy configuration. A buffer overflow flaw was found in the way libproxy handled the downloading of proxy auto-configuration (PAC) files. A malicious server hosting a PAC file or a man-in-the-middle attacker could use this flaw to cause an application using libproxy to crash or, possibly, execute arbitrary code, if the proxy settings obtained by libproxy (from the environment or the desktop environment settings) instructed the use of a PAC proxy configuration. (CVE-2012-4505) This issue was discovered by the Red Hat Security Response Team. Users of libproxy should upgrade to these updated packages, which contain a backported patch to correct this issue. All applications using libproxy must be restarted for this update to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5. Bugs fixed (http://bugzilla.redhat.com/): 864612 - CVE-2012-4505 libproxy: PAC handling insufficient content length check leading to buffer overflow |

| Title: | DSA-2571-1 libproxy - buffer overflow | ||
| Description: | 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. | ||
