Detailed vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to the mcopy function in softmagic.c in file 5.x, as used in the Fileinfo component in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8, does not properly restrict a certain offset value. A remote attacker can cause the service to crash or execute arbitrary code via a crafted string that is mishandled by a "Python script text executable" rule.
Successful exploitation of the vulnerability may result in system compromise.
