Description

This security bulletin contains information about 2 vulnerabilities.


1) Memory corruption (CVE-ID: CVE-2016-10713)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to cause DoS condition on the target system.

The weakness exists due to out-of-bounds access within pch_write_line() in pch.c. A local attacker can supply a specially crafted input, trigger memory corruption and cause the system to crash.

2) Double Free (CVE-ID: CVE-2018-6952)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing untrusted input within the another_hunk() function in pch.c. A remote attacker can create a specially crafted file, trick the victim into using in with the affected application, trigger a double free error and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
