Description

This security bulletin contains information about 4 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2015-0848)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

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:U/U:Amber


The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.

The weakness exists due to heap-based buffer overflow. A remote attacker can trick the victim into opening a specially crafted BMP image, trigger memory corruption and cause the service to crash or execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.


2) Heap-based buffer overflow (CVE-ID: CVE-2015-4588)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

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:U/U:Amber


The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.

The weakness exists  in the DecodeImage function due to heap-based buffer overflow. A remote attacker can trick the victim into opening a specially crafted "run-length count" in an image in a WMF file, trigger memory corruption and cause the service to crash or execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.


3) Out-of-bounds read (CVE-ID: CVE-2015-4695)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/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 DecodeImage function due to out-of-bounds read. A remote attacker can trigger memory corruption and cause the service to crash via a specially crafted WMF file.


4) Use-after-free error (CVE-ID: CVE-2015-4696)

CWE-ID: CWE-416 - Use After Free

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 due to use-after-free error. A remote attacker can trick the victim into opening a specially crafted WMF file to the (1) wmf2gd or (2) wmf2eps command, trigger memory corruption and cause the service to crash.
