Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2020-0053)
Summary:	The remote host is missing an update for the 'mbedtls' package(s) announced via the MGASA-2020-0053 advisory.
Description:	Summary: The remote host is missing an update for the 'mbedtls' package(s) announced via the MGASA-2020-0053 advisory. Vulnerability Insight: This update from mbedTLS 2.16.2 to mbedTLS 2.16.4 fixes several security vulnerabilities, among which: The deterministic ECDSA calculation reused the scheme's HMAC-DRBG to implement blinding. Because of this for the same key and message the same blinding value was generated. This reduced the effectiveness of the countermeasure and leaked information about the private key through side channels (CVE-2019-16910). Fix side channel vulnerability in ECDSA. Our bignum implementation is not constant time/constant trace, so side channel attacks can retrieve the blinded value, factor it (as it is smaller than RSA keys and not guaranteed to have only large prime factors), and then, by brute force, recover the key (CVE-2019-18222). See release notes for details. Affected Software/OS: 'mbedtls' package(s) on Mageia 7. Solution: Please install the updated package(s). CVSS Score: 2.6 CVSS Vector: AV:N/AC:H/Au:N/C:P/I:N/A:N
