Summary

The asn1_get_bit_der function in GNU Libtasn1 prior to version 3.6 fails to correctly handle a negative bit length when processing ASN.1 data. This oversight can lead to out-of-bounds access, allowing context-dependent attackers to exploit the vulnerability by submitting maliciously crafted ASN.1 data. This vulnerability highlights the importance of proper error handling in software libraries to mitigate potential security risks.
