High

Published: 05/06/2014(UTC)Translated: 17/06/2026(UTC)NVD NIST

Summary

The asn1_get_bit_der function in GNU Libtasn1 before version 3.6 does not properly report an error when a negative bit length is identified, allowing context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data.

Risk Assessment

Attackers may exploit this vulnerability to perform attacks that could lead to unauthorized memory access, potentially resulting in data leakage or system crashes.

Recommendation

It is recommended to update GNU Libtasn1 to version 3.6 or later to mitigate this vulnerability and to monitor systems for potential exploitation attempts.
