CVE-2006-4339 | BDVDB-2026-18977 Detail
Red HatRed Hat Enterprise Linux 3
Description#
A flaw was found in OpenSSL. When configured to use an RSA key with exponent 3, OpenSSL improperly removes PKCS-1 padding before generating a hash. This allows remote attackers to forge PKCS #1 v1.5 signatures. Consequently, OpenSSL may incorrectly verify X.509 and other certificates, leading to a bypass of trust and authentication mechanisms.
Impact#
Per CVSS v3.1: confidentiality impact high, integrity impact high, availability impact none. Attack vector: network.
Weaknesses#
- CWE-347 Improper Verification of Cryptographic Signature
