Summary
libcryptx-perl vulnerabilities
Details

It was discovered that CryptX did not verify authentication tags while performing GCM and ChaCha20-Poly1305 decryption. An attacker could possibly use this issue to cause CryptX to accept modified ciphertext, leading to data integrity violations or authentication bypass. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-25099)

It was discovered that CryptX included a version of the tomcrypt library that was susceptible to malformed unicode handling. An attacker could possibly use this issue to cause unexpected behavior or incorrect processing of crafted input. This issue only affected Ubuntu 18.04 LTS. (CVE-2025-40912)

It was discovered that CryptX included a version of the libtommath library that was susceptible to an integer overflow. An attacker could possibly use this issue to cause memory corruption or a denial of service. (CVE-2025-40914)
