Debian DLA-438-1 : libebml security update

medium Nessus Plugin ID 88999

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Two security-related issues were fixed in libebml, a library for accessing the EBML format :

CVE-2015-8790

The EbmlUnicodeString::UpdateFromUTF8 function in libEBML before 1.3.3 allows context-dependent attackers to obtain sensitive information from process heap memory via a crafted UTF-8 string, which triggers an invalid memory access.

CVE-2015-8791

The EbmlElement::ReadCodedSizeValue function in libEBML before 1.3.3 allows context-dependent attackers to obtain sensitive information from process heap memory via a crafted length value in an EBML id, which triggers an invalid memory access.

For Debian 6 'squeeze', these issues have been fixed in libebml version 0.7.7-3.1+deb6u1. We recommend you to upgrade your libebml packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected libebml-dev, and libebml0 packages.
