Detail

Product: Solaris 9 Operating System Solaris 10 Operating System Solaris 8 Operating System

A security vulnerability in the Solaris X Window System (X(5)) PCF font handler in libfont and libXfont libraries may allow a remote unprivileged user to crash the application or execute arbitrary code with the privileges of the application which dynamically links to one of these libraries. The ability to crash an application is a type of Denial of Service (DoS).

This issue is described in the following documents:

Title: DSA-1466 xfree86 -- several vulnerabilities
Description: The X.org fix for CVE-2007-6429 introduced a regression in the MIT-SHM extension, which prevented the start of a few applications. This update provides updated packages for the xfree86 version included in Debian old stable (sarge) in addition to the fixed packages for Debian stable (etch), which were provided in DSA 1466-2. For reference the original advisory text below: Several local vulnerabilities have been discovered in the X.Org X server. The Common Vulnerabilities and Exposures project identifies the following problems: regenrecht discovered that missing input sanitising within the XFree86-Misc extension may lead to local privilege escalation. It was discovered that error messages of security policy file handling may lead to a minor information leak disclosing the existence of files otherwise inaccessible to the user. regenrecht discovered that missing input sanitising within the XInput-Misc extension may lead to local privilege escalation. regenrecht discovered that missing input sanitising within the TOG-CUP extension may lead to disclosure of memory contents. regenrecht discovered that integer overflows in the EVI and MIT-SHM extensions may lead to local privilege escalation. It was discovered that insufficient validation of PCF fonts could lead to local privilege escalation.
