A vulnerability classified as very critical was found in ghostscript 8.64/8.70 (Document Processing Software). Affected by this vulnerability is the function errprintf of the file base/gsmisc.c of the component Logging. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in the errprintf function in base/gsmisc.c in ghostscript 8.64 through 8.70 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted PDF file, as originally reported for debug logging code in gdevcups.c in the CUPS output driver.

The weakness was shared 12/18/2009 as Bug 540760 as not defined bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. This vulnerability is known as CVE-2009-4270 since 12/10/2009. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/30/2021).

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 47815 (openSUSE Security Update : ghostscript-devel (openSUSE-SU-2010:0425-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 120132 (Solaris Multiple Vulnerabilities in Ghostscript).

A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (47815). The entries 53273 and 53158 are related to this item.
