{"id":"MGASA-2020-0293","summary":"Updated mbedtls packages fix security vulnerability","details":"Updated mbedtls packages fix security vulnerabilities\n\nFix a side channel vulnerability in modular exponentiation that could reveal\nan RSA private key used in a secure enclave.\n\nFix side channel in mbedtls_ecp_check_pub_priv() and mbedtls_pk_parse_key() /\nmbedtls_pk_parse_keyfile() (when loading a private key that didn't include the\nuncompressed public key), as well as mbedtls_ecp_mul() /\nmbedtls_ecp_mul_restartable() when called with a NULL f_rng argument. An\nattacker with access to precise enough timing and memory access information\n(typically an untrusted operating system attacking a secure enclave) could\nfully recover the ECC private key. \n\nFix issue in Lucky 13 counter-measure that could make it ineffective when\nhardware accelerators were used (using one of the MBEDTLS_SHAxxx_ALT macros).\nThis would cause the original Lucky 13 attack to be possible in those\nconfigurations, allowing an active network attacker to recover plaintext after\nrepeated timing measurements under some conditions.\n","modified":"2026-04-16T04:25:48.165301Z","published":"2020-07-10T15:40:08Z","references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2020-0293.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=26924"},{"type":"ADVISORY","url":"https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2020-07"},{"type":"WEB","url":"https://github.com/ARMmbed/mbedtls/releases/tag/mbedtls-2.16.7"}],"affected":[{"package":{"name":"mbedtls","ecosystem":"Mageia:7","purl":"pkg:rpm/mageia/mbedtls?arch=source&distro=mageia-7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.16.7-1.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2020-0293.json"}}],"schema_version":"1.7.5","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
