Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Resource exhaustion
EUVDB-ID: #VU19048
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-2017-12806
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to memory exhaustion when processing images within the format8BIM() function. A remote attacker can create a specially crafted image, pass it to the affected application and consume all available memory on the system.
MitigationInstall updates from vendor's website.
Vulnerable software versionsImageMagick: 7.0.6-6
CPE2.3 External linkshttps://github.com/ImageMagick/ImageMagick/issues/660
Q & A
Can this vulnerability be exploited remotely?
