Gentoo Linux Security Advisory

Title: file: Stack-based buffer overflow (GLSA 201710-02)
Severity: normal
Exploitable: remote
Date: 2017-10-08
Bug(s): #629872
ID: 201710-02

Synopsis

A stack-based buffer overflow was found in file, possibly resulting
in the 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: < 5.32
Unaffected: >= 5.32
Architectures: All supported architectures


Description

An issue discovered in file allows attackers to write 20 bytes to the
stack buffer via a specially crafted .notes section.


Impact

A remote attacker, by using a specially crafted .notes section in an ELF
binary, could execute arbitrary code or cause a Denial of Service
condition.


Workaround

There is no known workaround at this time.

Resolution

All file users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=sys-apps/file-5.32"
