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.
