Severity:	normal
Title:	GNU Libtasn1: Multiple vulnerabilities
Date:	10/13/2017
Bugs:	#619686, #627014
ID:	201710-11

Synopsis

Multiple vulnerabilities have been found in GNU Libtasn1, the worst of which may allow remote attackers to execute arbitrary code.

Background

A library that provides Abstract Syntax Notation One (ASN.1, as specified by the X.680 ITU-T recommendation) parsing and structures management, and Distinguished Encoding Rules (DER, as per X.690) encoding and decoding functions.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-libs/libtasn1	< 4.12-r1	>= 4.12-r1	All supported architectures

Description

Multiple vulnerabilities have been discovered in GNU Libtasn1. Please review the referenced CVE identifiers for details.

Impact

A remote attacker could possibly execute arbitrary code with the privileges of the process, cause a Denial of Service condition, or have other unspecified impacts.

Workaround

There is no known workaround at this time.

Resolution

All GNU Libtasn1 users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/libtasn1-4.12-r1"

Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
