Packages
- libcryptx-perl - Perl modules providing cryptography based on LibTomCrypt library
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.
