Описание
The mconvert function in softmagic.c in file before 5.21, as used in the Fileinfo component in PHP before 5.4.37, 5.5.x before 5.5.21, and 5.6.x before 5.6.5, does not properly handle a certain string-length field during a copy of a truncated version of a Pascal string, which might allow remote attackers to cause a denial of service (out-of-bounds memory access and application crash) via a crafted file.
An ouf-of-bounds read flaw was found in the way the file utility processed certain Pascal strings. A remote attacker could cause an application using the file utility (for example, PHP using the fileinfo module) to crash if it was used to identify the type of the attacker-supplied file.
