SUSE CVE-2026-63076

Issue summary: OpenSSL CMP password based protection verification only checks whether the protectionAlg parameter was not NULL and not its ASN.1 type, before treating it as a PBMParameter. A crafted message can contain a parameter of a different type, which is then dereferenced as an invalid...

SUSE CVE-2026-63073

Issue summary: OpenSSL CMP response validation passed an unexpected response sender distinguished name directly as the format string to ERRraisedata. Impact summary: A malicious or intercepted CMP endpoint can crash a CMP client that enforces an expected sender or uses a pinned server certificate...

Use of Externally-Controlled Format String

Overview Affected versions of this package are vulnerable to Use of Externally-Controlled Format String in osslcmpmsgcheckupdate in crypto/cmp/cmpvfy.c. An attacker can crash a CMP client by sending an unexpected response with a sender distinguished name containing format specifiers such as %s or...
