Ubuntu 6.06 LTS / 8.04 LTS / 8.10 : ghostscript, gs-esp, gs-gpl vulnerabilities (USN-757-1)

Ubuntu Security Notice (C) 2009-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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).

Solution :

Update the affected packages.
