Gentoo Linux Security Advisory

Title: file: Integer overflow (GLSA 200705-25)
Severity: high
Exploitable: remote
Date: May 31, 2007
Updated: June 01, 2007
Bug(s): #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: sys-apps/file
Vulnerable: < 4.21
Unaffected: >= 4.21
Architectures: x86 ppc hppa


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=sys-apps/file-4.21"


References

CVE-2007-2799
