Software vendor:
GNU

Description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

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


Remediation

Install update from vendor's website.
