Security Bulletin

This security bulletin contains information about 16 vulnerabilities.

1) Division by zero

EUVDB-ID: #VU32099

Risk: Medium

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2016-10267

CWE-ID: CWE-369 - Divide By Zero

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to divide-by-zero error within LibTIFF 4.0.7. A remote attacker can perform a denial of service (divide-by-zero error and application crash) via a crafted TIFF image, related to libtiff/tif_ojpeg.c:816:8.

Mitigation

Update the affected packages.
media-libs/tiff to version: 4.0.8

Vulnerable software versions

Gentoo Linux: All versions

CPE2.3 External links

https://security.gentoo.org/
https://security.gentoo.org/glsa/201709-27


Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Memory corruption

EUVDB-ID: #VU12653

Risk: Low

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.
