Synopsis ========
A vulnerability in Libtasn1 might cause a Denial of Service condition.
Background ==========
Libtasn1 is a library used to parse ASN.1 (Abstract Syntax Notation One) objects, and perform DER (Distinguished Encoding Rules) decoding.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libtasn1 < 2.12 >= 2.12
Description ===========
Libtasn1 does not properly handle length fields when performing DER decoding.
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Libtasn1 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libtasn1-2.12"
Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
