GLSA-201209-12 : Libtasn1: Denial of Service
Medium Nessus Plugin ID 62302
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201209-12 (Libtasn1: Denial of Service)
Libtasn1 does not properly handle length fields when performing DER decoding.
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.
SolutionAll 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.
