CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability classified as very critical has been found in HTMLDOC 1.8.24/1.8.25/1.8.26/1.8.27. This affects the function set_page_size in the library htmllib.cxx of the file util.cxx. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in the set_page_size function in util.cxx in HTMLDOC 1.8.27 and earlier allows context-dependent attackers to execute arbitrary code via a long MEDIA SIZE comment. NOTE: it was later reported that there were additional vectors in htmllib.cxx and ps-pdf.cxx using an AFM font file with a long glyph name, but these vectors do not cross privilege boundaries.

The weakness was disclosed 09/02/2009 (oss-sec). The advisory is shared at openwall.com. This vulnerability is uniquely identified as CVE-2009-3050 since 09/02/2009. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. 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 08/21/2021).

The vulnerability scanner Nessus provides a plugin with the ID 40959 (GLSA-200909-12 : HTMLDOC: User-assisted execution of arbitrary code), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165245 (SUSE Security Update for Multiple Packages (SUSE-SR:2009:020)).
