Kategorie:	Mageia Linux Local Security Checks
Titel:	Mageia: Security Advisory (MGASA-2020-0023)
Zusammenfassung:	The remote host is missing an update for the 'compat-openssl10, openssl' package(s) announced via the MGASA-2020-0023 advisory.
Beschreibung:	Summary: The remote host is missing an update for the 'compat-openssl10, openssl' package(s) announced via the MGASA-2020-0023 advisory. Vulnerability Insight: Updated compat-openssl10 and openssl packages fix security vulnerability: There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. Also applications directly using the low level API BN_mod_exp may be affected if they use BN_FLG_CONSTTIME (CVE-2019-1551). Affected Software/OS: 'compat-openssl10, openssl' 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
