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
-------------------------------------------------------------------
1 dev-libs/libtasn1 < 4.12-r1 >= 4.12-r1
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.
