Summary: Updated libtasn1 packages that fix three security issues are now available for Red Hat Enterprise Linux 7. The Red Hat Security Response Team has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: The libtasn1 library provides Abstract Syntax Notation One (ASN.1) parsing and structures management, and Distinguished Encoding Rules (DER) encoding and decoding functions. It was discovered that the asn1_get_bit_der() function of the libtasn1 library incorrectly reported the length of ASN.1-encoded data. Specially crafted ASN.1 input could cause an application using libtasn1 to perform an out-of-bounds access operation, causing the application to crash or, possibly, execute arbitrary code. (CVE-2014-3468) Multiple incorrect buffer boundary check issues were discovered in libtasn1. Specially crafted ASN.1 input could cause an application using libtasn1 to crash. (CVE-2014-3467) Multiple NULL pointer dereference flaws were found in libtasn1's asn1_read_value() function. Specially crafted ASN.1 input could cause an application using libtasn1 to crash, if the application used the aforementioned function in a certain way. (CVE-2014-3469) Red Hat would like to thank GnuTLS upstream for reporting these issues. All libtasn1 users are advised to upgrade to these updated packages, which correct these issues. For the update to take effect, all applications linked to the libtasn1 library must be restarted. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1102022 - CVE-2014-3467 libtasn1: multiple boundary check issues 1102323 - CVE-2014-3468 libtasn1: asn1_get_bit_der() can return negative bit length 1102329 - CVE-2014-3469 libtasn1: asn1_read_value_type() NULL pointer dereference 6.
