Apple Mac OS X dynamic linker privileged application manipulation
| macosx-dynamic-linker-manipulation (28140) |  Medium Risk |
Description:
Apple Mac OS X and Mac OS X Server could allow a local attacker to modify privileged application functionality and possibly gain elevated privileges on the system, caused by a vulnerability in the dynamic linker (dyld) daemon. An attacker could exploit this vulnerability by specifying certain dynamic linker options that would cause malicious data to be written to standard error output, which could later be used to manipulate the functionality of privileged applications that parse or reuse the error output.
