Severity: High Title: file: Integer overflow Date: May 31, 2007 Bugs: #179583 ID: 200705-25

Synopsis ========
An integer overflow vulnerability has been reported in file allowing for the user-assisted execution of arbitrary code.
Background ==========
file is a utility that guesses a file format by scanning binary data for patterns.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/file < 4.21 >= 4.21 ------------------------------------------------------------------- # Package 1 only applies to x86, PPC and HPPA users.
Description ===========
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.
Resolution ==========
Since file is a system package, all Gentoo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/file-4.21"
