MGASA-2024-0297 Updated botan2 packages fix security vulnerability

An attacker could present an ECDSA X.509 certificate using explicit encoding where the parameters are very large. When parsing, the parameter is checked to be prime, causing excessive computation. This was patched in 2.19.4 and 3.3.0 to allow the prime parameter of the elliptic curve to be at mos...

UBUNTU-CVE-2024-34703

Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or using explicit encoding of the parameters. Prior to versions 3.3.0 and 2.19.4, an attacker could present an ECDSA X.509 certificate using explicit encoding where the parameter...
