A vulnerability in Libtasn1 might cause a Denial of Service condition.
|Package||dev-libs/libtasn1 on all architectures|
|Affected versions||< 2.12|
|Unaffected versions||>= 2.12|
Libtasn1 is a library used to parse ASN.1 (Abstract Syntax Notation One) objects, and perform DER (Distinguished Encoding Rules) decoding.
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.
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.
