December 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 JBIGDecode() of
LibTIFF, in order to trigger a denial of service, and possibly to
run code.
Impacted products: Debian, LibTIFF, openSUSE Leap, SUSE Linux
Enterprise Desktop, SLES, WindRiver Linux.
Severity: 2/4.
Consequences: user access/rights, denial of service on service,
denial of service on client.
Provenance: document.
Confidence: confirmed by the editor (5/5).
Creation date: 23/10/2018.
DESCRIPTION OF THE VULNERABILITY
The LibTIFF product offers a web service.
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
JBIGDecode() of LibTIFF, in order to trigger a denial of service,
and possibly to run code.
