|Gentoo Linux Security Advisory
Title: Libtasn1: Denial of Service (GLSA 201209-12)
Date: September 25, 2012
A vulnerability in Libtasn1 might cause a Denial of Service
Libtasn1 is a library used to parse ASN.1 (Abstract Syntax Notation One)
objects, and perform DER (Distinguished Encoding Rules) decoding.
Vulnerable: < 2.12
Unaffected: >= 2.12
Architectures: All supported architectures
Libtasn1 does not properly handle length fields when performing DER
A remote attacker could entice a user to open a specially crafted
DER-encoded object in an application linked against Libtasn1, possibly
resulting in Denial of Service.
There is no known workaround at this time.
All Libtasn1 users should upgrade to the latest version:
Packages which depend on this library may need to be recompiled. Tools
|# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libtasn1-2.12"
such as revdep-rebuild may assist in identifying some of these packages.
