Ghostscript is a set of software that provides a PostScript interpreter, a set of C procedures (the
Ghostscript library, which implements the graphics capabilities in the PostScript language) and an
interpreter for Portable Document Format (PDF) files.
It was discovered that the Red Hat Security Advisory RHSA-2009:0345 did not address all possible
integer overflow flaws in Ghostscript's International Color Consortium Format library (icclib). Using
specially-crafted ICC profiles, an attacker could create a malicious PostScript or PDF file with
embedded images that could cause Ghostscript to crash or, potentially, execute arbitrary code when
opened. (CVE-2009-0792
A buffer overflow flaw and multiple missing boundary checks were found in Ghostscript. An attacker
could create a specially-crafted PostScript or PDF file that could cause Ghostscript to crash
or, potentially, execute arbitrary code when opened.
