The remote host is affected by the vulnerability described in GLSA-200705-25 (file: Integer overflow)
Colin Percival from FreeBSD reported that the previous fix for the file_printf() buffer overflow introduced a new integer overflow.
Impact :
A remote attacker could entice a user to run the file program on an overly large file (more than 1Gb) that would trigger an integer overflow on 32-bit systems, possibly leading to the execution of arbitrary code with the rights of the user running file.
Workaround :
There is no known workaround at this time.
