It was discovered that Ghostscript contained a buffer underflow in its CCITTFax decoding filter. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2007-6725)
It was discovered that Ghostscript contained a buffer overflow in the BaseFont writer module. If a user or automated system were tricked into opening a crafted Postscript file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program.

A security issue affects these releases of Ubuntu and its derivatives:
It was discovered that Ghostscript contained a buffer underflow in its CCITTFax decoding filter. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2007-6725)
It was discovered that Ghostscript contained a buffer overflow in the BaseFont writer module. If a user or automated system were tricked into opening a crafted Postscript file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2008-6679)
It was discovered that Ghostscript contained additional integer overflows in its ICC color management library. If a user or automated system were tricked into opening a crafted Postscript or PDF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0792)
Alin Rad Pop discovered that Ghostscript contained a buffer overflow in the jbig2dec library. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0196)
USN-743-1 provided updated ghostscript and gs-gpl packages to fix two security vulnerabilities. This update corrects the same vulnerabilities in the gs-esp package.
Original advisory details: It was discovered that Ghostscript contained multiple integer overflows in its ICC color management library. If a user or automated system were tricked into opening a crafted Postscript file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0583)
It was discovered that Ghostscript did not properly perform bounds checking in its ICC color management library. If a user or automated system were tricked into opening a crafted Postscript file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0584)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system upgrade is sufficient to effect the necessary changes.
