CVE-2005-3191
CWE-119Published: December 7, 2005· Updated: Jun 16, 2026
Official Description
Multiple heap-based buffer overflows in the (1) DCTStream::readProgressiveSOF and (2) DCTStream::readBaselineSOF functions in the DCT stream parsing code (Stream.cc) in xpdf 3.01 and earlier, as used in products such as (a) Poppler, (b) teTeX, (c) KDE kpdf, (d) pdftohtml, (e) KOffice KWord, (f) CUPS, and (g) libextractor allow user-assisted attackers to cause a denial of service (heap corruption) and possibly execute arbitrary code via a crafted PDF file with an out-of-range number of components (numComps), which is used as an array index.
Technical Analysis
CVE-2005-3191 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
