Multiple vulnerabilities have been found in GNU Libtasn1, the worst of which may allow remote attackers to execute arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/libtasn1 | * | < 4.12-r1 | >= 4.12-r1 |
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.
Multiple vulnerabilities have been discovered in GNU Libtasn1. Please review the referenced CVE identifiers for details.
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.
There is no known workaround at this time.
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.
A vulnerability in Libtasn1 allows remote attackers to cause a Denial of Service condition.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/libtasn1 | * | < 4.8 | >= 4.8 |
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"
Multiple vulnerabilities have been found in libtasn1, the worst of which could lead to arbitrary code execution.

| dev-libs/libtasn1 | * | < 2.12 | >= 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.
A flaw in the parsing of Distinguished Encoding Rules (DER) has been discovered in libtasn1, potentially resulting in the execution of arbitrary code.

Libtasn1 is a library used to parse ASN.1 (Abstract Syntax Notation One) objects, and perform DER (Distinguished Encoding Rules) decoding. Libtasn1 is included with the GNU TLS library, which is used by applications to provide a cryptographically secure communications channel.
Evgeny Legerov has reported a flaw in the DER decoding routines provided by libtasn1, which could cause an out of bounds access to occur.
A remote attacker could cause an application using libtasn1 to crash and potentially execute arbitrary code by sending specially crafted input.
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/libtasn1-0.2.18"
All GNU TLS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-libs/gnutls-1.2.10"
