CVE-2026-44378
Last modified
CVE-2026-44378 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. EPSS estimates a 0.32% chance of exploitation in the next 30 days.
Description
Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which prohibits indefinite length encodings. This vulnerability is fixed in 3.12.0.
