Synopsis ========
A vulnerability in Libtasn1 allows remote attackers to cause a Denial of Service condition.
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 < 4.8 >= 4.8
Description ===========
Libtasn1 does not correctly handle certain malformed DER certificates.
Impact ======
A remote attacker could entice a user or automated system to process a specially crafted certificate using Libtasn1, resulting in a Denial of Service condition.
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/libtasn1-4.8"
References ==========
