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. 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. 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. 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)).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
