Summary

The remote host is missing an update for the 'libtasn1' package(s) announced via the referenced advisory.

Insight

Insight

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.
