Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Memory corruption

EUVDB-ID: #VU12653

Risk: Low

CVSSv4.0: 1.2 [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]

CVE-ID: CVE-2016-10268

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The weakness exists due to integer underflow and heap-based buffer under-read. A remote attacker can trick the victim into opening a specially crafted TIFF image, related to "READ of size 78490" and libtiff/tif_unix.c:115:23, trigger memory corruption and cause the service to crash.

Mitigation

Install update from vendor's website.

2) Out-of-bounds write

EUVDB-ID: #VU12655

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-2016-9453

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

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

The weakness exists in the t2p_readwrite_pdf_image_tile function due to out-of-bounds write. A remote attacker can trick the victim into opening a specially crafted JPEG file with a TIFFTAG_JPEGTABLES of length one and cause the service to rash or execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Install update from vendor's website.
