Security Bulletin
This security bulletin contains information about 7 vulnerabilities.
1) Integer overflow
EUVDB-ID: #VU7414
Risk: High
CVSSv4.0: 5.7 [CVSS:4.0/AV:L/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-2017-2820
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exist due to integer overflow in the JPEG 2000 image parsing functionality when handling malicious data. A remote attacker can send a specially crafted PDF file, trick the victim into opening it, trigger out of bounds memory overwrite on the heap and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected packages.
