Vigil@nce - TeX Live: buffer overflow via texlive-bin

November 2018 by Vigil@nce

This bulletin was written by Vigil@nce : https://vigilance.fr/offer

SYNTHESIS OF THE VULNERABILITY

An attacker can generate a buffer overflow via texlive-bin of TeX
Live, in order to trigger a denial of service, and possibly to run
code.

Impacted products: Debian, openSUSE Leap, SUSE Linux Enterprise
Desktop, SLES, Ubuntu.

Severity: 2/4.

Creation date: 21/09/2018.

DESCRIPTION OF THE VULNERABILITY

The TeX Live product processes Tex documents.

However, if the size of data is greater than the size of the
storage array, an overflow occurs.

An attacker can therefore generate a buffer overflow via
texlive-bin of TeX Live, in order to trigger a denial of service,
and possibly to run code.
