Description SMASH SMASH 2024-01-30 08:59:42 UTC 
CVE-2024-23775 Buffer overflow in mbedtls_x509_set_extension().

When writing x509 extensions we failed to validate inputs passed in to mbedtls_x509_set_extension(), which could result in an integer overflow, causing a zero-length buffer to be allocated to hold the extension. The extension would then be copied into the buffer, causing a heap buffer overflow.

Resolution: update net-libs/mbedtls to 2.28.7 and 3.5.2.
