ghostscript vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS
Summary:
Ghostscript could be made to crash or run programs as your login if it opened a specially crafted file.
Software Description: - ghostscript: The GPL Ghostscript PostScript/PDF interpreter
Details:
It was discovered that Ghostscript did not correctly handle memory allocation when parsing certain malformed JPEG-2000 images. If a user or automated system were tricked into opening a specially crafted image, an attacker could cause a denial of service and possibly execute arbitrary code with user privileges. (CVE-2008-3520)
It was discovered that Ghostscript did not correctly handle certain formatting operations when parsing JPEG-2000 images. If a user or automated system were tricked into opening a specially crafted image, an attacker could cause a denial of service and possibly execute arbitrary code with user privileges. (CVE-2008-3522)
It was discovered that Ghostscript incorrectly handled certain malformed TrueType fonts. If a user or automated system were tricked into opening a document containing a specially crafted font, an attacker could cause a denial of service and possibly execute arbitrary code with user privileges. This issue only affected Ubuntu 8.04 LTS. (CVE-2009-3743)
It was discovered that Ghostscript incorrectly handled certain malformed Type 2 fonts. If a user or automated system were tricked into opening a document containing a specially crafted font, an attacker could cause a denial of service and possibly execute arbitrary code with user privileges. This issue only affected Ubuntu 8.04 LTS. (CVE-2010-4054)
Jonathan Foote discovered that Ghostscript incorrectly handled certain malformed JPEG-2000 image files. If a user or automated system were tricked into opening a specially crafted JPEG-2000 image file, an attacker could cause Ghostscript to crash or possibly execute arbitrary code with user privileges. (CVE-2011-4516, CVE-2011-4517)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 10.10: libgs8 8.71.dfsg.2-0ubuntu7.1
Ubuntu 10.04 LTS: libgs8 8.71.dfsg.1-0ubuntu5.4
Ubuntu 8.04 LTS: libgs8 8.61.dfsg.1-1ubuntu3.4
