"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.

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).
