Red Hat Security Advisory 2014-0596-01 - The libtasn1 library provides Abstract Syntax Notation One parsing and structures management, and Distinguished Encoding Rules 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. Multiple incorrect buffer boundary check issues were discovered in libtasn1. Specially crafted ASN.1 input could cause an application using libtasn1 to crash.
