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.
Libtasn1 does not correctly handle certain malformed DER certificates.
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.
There is no known workaround at this time.
All Libtasn1 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libtasn1-4.8"
