Description

This security bulletin contains information about 2 vulnerabilities.


1) Uncontrolled memory allocation (CVE-ID: CVE-2016-9011)

CWE-ID: CWE-789 - Uncontrolled Memory Allocation

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


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

The weakness exists in the wmf_malloc function in api.c due to uncontrolled memory allocation. A remote attacker can trick the victim into opening a specially crafted wmf file, trigger memory corruption and cause the service to crash.


2) Double Free (CVE-ID: CVE-2019-6978)

CWE-ID: CWE-415 - Double Free

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 vulnerability exists due to double free in the gdImage*Ptr() functions in gd_gif_out.c, gd_jpeg.c, and gd_wbmp.c. A remote attacker can trick the victim into opening a specially crafted input, trigger double free error and execute arbitrary code on the target system.

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