AZL-97665 CVE-2026-63072 affecting package openssl-fips-provider 3.1.2-2

Issue summary: OpenSSL CMS decryption sizes the key-unwrap output buffer based on querying the unwrapped key size, but the AES-WRAP-PAD unwrap primitive can write and cleanse more bytes than that query reports, causing an 8-byte out-of-bounds heap write. Impact summary: An attacker who supplies a...

CVE-2026-63072

The OpenSSL library is vulnerable to an 8-byte out-of-bounds heap write during CMS decryption via the public CMS_decrypt() function. The root cause is that the code sizes the key-unwrap output buffer based on a query of the unwrapped key size, but the AES-WRAP-PAD unwrap primitive can write and c...
