ImageMagick XCF decoder PROP_USER_UNIT buffer overflow
| imagemagick-propuserunit-bo (28575) |  High Risk |
Description:
ImageMagick is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the PROP_USER_UNIT when handling the ReadBlobStringWithLongSize() function. By creating a malicious XCF image, a remote attacker could overflow a buffer and execute arbitrary code on the system, if the attacker could persuade the victim to open the malicious image.
