This month

MEDIUM 5.1DOWNGRADE

CVE-2005-3193 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.

Heap-based buffer overflow in the JPXStream::readCodestream function in the JPX stream parsing code (JPXStream.c) for xpdf 3.01 and earlier, as used in products such as (1) Poppler, (2) teTeX, (3) KDE kpdf, (4) CUPS, and (5) libextractor allows user-assisted attackers to cause a denial of service (heap corruption) and possibly execute arbitrary code via a crafted PDF file with large size values that cause insufficient memory to be allocated.

Why this priority

EPSS top 9%: very likely to be exploited

No fix is published yet: follow the downgrade or mitigation steps.

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.
