Description
A programming error exists in a way Randombit Botan cryptographic library
version 2.0.1 implements x500 string comparisons which could lead to
certificate verification issues and abuse. A specially crafted X509
certificate would need to be delivered to the client or server application
in order to trigger this vulnerability.
Ubuntu-Description
It was discovered that Botan did not properly manage x509 DN strings
comparisons when provided with a specially crafted X509 certificate. An
attacker could possibly use this issue to cause out of bound reads,
resulting in information leakage, denial of service, or potentially
incorrect certificate validation results.
