golang-fips: Golang FIPS zeroed buffer

A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted...

CVE-2026-14957

In FIPS mode, Libreswan's adddecodedcert function calls CERTExtractPublicKey and asserts that the result is not NULL. However, CERTExtractPublicKey returns NULL when public key extraction fails, for example if the RSA exponent is set to 0. A remote attacker can send a malformed X.509 certificate ...

AZL-98441 CVE-2026-14957 affecting package libreswan for versions less than 4.15-3

In FIPS mode, Libreswan's adddecodedcert function calls CERTExtractPublicKey and asserts that the result is not NULL. However, CERTExtractPublicKey returns NULL when public key extraction fails, for example if the RSA exponent is set to 0. A remote attacker can send a malformed X.509 certificate ...

CVE-2026-14957

CVE-2026-14957 is a denial-of-service vulnerability in Libreswan (an IPsec/IKE implementation for Linux). In FIPS mode , the add_decoded_cert() function calls CERT_ExtractPublicKey() and asserts the result is non-NULL. When public key extraction fails (e.g., RSA exponent set to 0), the assertion ...
