Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU12349
Risk: High
CVSSv4.0: 6.1 [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]
CVE-ID: CVE-2015-0848
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected packages
Ubuntu: 12.04 - 14.04
CPE2.3 External linkshttps://www.ubuntu.com/usn/usn-2670-1/
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Heap-based buffer overflow
EUVDB-ID: #VU12350
Risk: High
CVSSv4.0: 6.1 [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]
CVE-ID: CVE-2015-4588
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe 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.

CVE-ID: CVE-2015-4696
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe 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.
