Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Stack-based buffer overflow
EUVDB-ID: #VU12166
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-1243
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the extractTree function due to stack-based buffer overflow. A remote attacker can execute arbitrary code via a long pathname.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected package to version: 0.7.11a-3+deb7u1, 0.7.11a-3+deb8u1, 0.7.11a-4
Vulnerable software versionsDebian Linux: All versions
External linkshttp://tmp.tjjr.fi/0001-Fix-unsafe-extraction-by-using-mkdir-instead-of-shel.patch
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) Improper input validation
EUVDB-ID: #VU12168
Risk: High
CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-1244
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the extractTree function due to improper input validation. A remote attacker can trick the victim into opening a specially crafted adf file and execute arbitrary code via shell metacharacters in a directory name.
Successful exploitation of the vulnerability may result in system compromise.
