{"id":"USN-8128-1","summary":"libcryptx-perl vulnerabilities","details":"It was discovered that CryptX did not verify authentication tags while\nperforming GCM and ChaCha20-Poly1305 decryption. An attacker could possibly\nuse this issue to cause CryptX to accept modified ciphertext, leading to\ndata integrity violations or authentication bypass. This issue only\naffected Ubuntu 18.04 LTS. (CVE-2018-25099)\n\nIt was discovered that CryptX included a version of the tomcrypt library\nthat was susceptible to malformed unicode handling. An attacker could\npossibly use this issue to cause unexpected behavior or incorrect\nprocessing of crafted input. This issue only affected Ubuntu 18.04 LTS.\n(CVE-2025-40912)\n\nIt was discovered that CryptX included a version of the libtommath library\nthat was susceptible to an integer overflow.
