Description
This security bulletin contains information about 1 vulnerability.
1) Memory corruption (CVE-ID: CVE-2017-2527)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to lack of bounds checking in CAMediaTimingFunctionBuiltin when processing malicious data. A remote attacker can send a specially crafted graphic file, trick the victim into opening it, trigger memory corruption in CoreAnimation and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in full system compromise.
