TITLE

Apple OS X of SecKeyDeriveFromPassword Vulnerability in function that can retrieve important information from process memory

Trust: 0.8

sources: JVNDB: JVNDB-2016-004980

DESCRIPTION

The SecKeyDeriveFromPassword function in Apple OS X before 10.12 does not use the CF_RETURNS_RETAINED keyword, which allows attackers to obtain sensitive information from process memory by triggering key derivation. Apple Mac OS X is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code, gain sensitive information, cause denial-of-service conditions, bypass security restrictions, and perform unauthorized actions. This may aid in other attacks. These issues are fixed in: Apple macOS 10.12
