Published: April 25, 2018
Vulnerability identifier: #VU12155
CSH Severity: Low
CVSS v4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
CVE-ID: CVE-2016-4333
CWE-ID: CWE-122
Exploitation vector: Local access
Exploit availability:
No public exploit available
Vulnerability details
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to the library allocating space for the array using a value from the file has an impact within the loop for initializing said array allowing a value within the file to modify the loop's terminator. A local attacker can cause the loop's index to point outside the bounds of the array when initializing it, trigger heap-based buffer overflow and execute arbitrary code with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
