Test ID:	1.3.6.1.4.1.25623.1.1.10.2020.0293
Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2020-0293)
Summary:	The remote host is missing an update for the 'mbedtls' package(s) announced via the MGASA-2020-0293 advisory.
Description:	Summary: The remote host is missing an update for the 'mbedtls' package(s) announced via the MGASA-2020-0293 advisory. Vulnerability Insight: Updated mbedtls packages fix security vulnerabilities Fix a side channel vulnerability in modular exponentiation that could reveal an RSA private key used in a secure enclave. Fix side channel in mbedtls_ecp_check_pub_priv() and mbedtls_pk_parse_key() / mbedtls_pk_parse_keyfile() (when loading a private key that didn't include the uncompressed public key), as well as mbedtls_ecp_mul() / mbedtls_ecp_mul_restartable() when called with a NULL f_rng argument. An attacker with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave) could fully recover the ECC private key. Fix issue in Lucky 13 counter-measure that could make it ineffective when hardware accelerators were used (using one of the MBEDTLS_SHAxxx_ALT macros). This would cause the original Lucky 13 attack to be possible in those configurations, allowing an active network attacker to recover plaintext after repeated timing measurements under some conditions. Affected Software/OS: 'mbedtls' package(s) on Mageia 7. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
