Description
A flaw was found in ImageMagick. A remote attacker could exploit this vulnerability by providing a specially crafted PCD (Picture CD) image file that lacks a valid Sync marker. This causes the DecodeImage() function to enter an infinite loop, leading to continuous CPU resource consumption and system resource exhaustion. The primary consequence is a denial of service (DoS), rendering the program unresponsive.
Statement
This MODERATE impact denial of service flaw in ImageMagick allows a remote attacker to cause continuous CPU resource consumption and system resource exhaustion. This occurs when processing a specially crafted PCD image file that lacks a valid Sync marker. Red Hat Enterprise Linux 6 ELS and 7 ELS are affected.
CVSS score applicability
The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
Mitigation
To mitigate this vulnerability, restrict ImageMagick's ability to process untrusted PCD files. If PCD file support is not required, consider disabling the PCD coder in ImageMagick's policy.xml configuration file. Add <policy domain="coder" rights="none" pattern="PCD" /> to /etc/ImageMagick-X/policy.xml (where X is the ImageMagick version). A service restart or application reload may be required for the changes to take effect.
