MEDIUM 5.1DOWNGRADE

CVE-2005-3191 is a medium-severity flaw (CVSS 5.1) affecting xpdf. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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

Affected: 0.90 · 0.91 · 0.92 · 0.93 · 1.0 · 1.0a · 1.1 · 2.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.90

1. Check installed version

apt-cache policy xpdf || rpm -q xpdf || xpdf --version

2. No fixed release: DOWNGRADE to a release before 0.90 (Debian / Ubuntu)

apt-cache madison xpdf sudo apt install xpdf=<VERSION_BEFORE_0.90> sudo apt-mark hold xpdf

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list xpdf sudo dnf downgrade xpdf-<VERSION_BEFORE_0.90> sudo dnf versionlock add xpdf

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
