Gentoo Linux Security Advisory

Title: JHead: Multiple vulnerabilities (GLSA 200901-02)
Severity: normal
Exploitable: remote
Date: January 11, 2009
Bug(s): #242702, #243238
ID: 200901-02

Synopsis

Multiple vulnerabilities in JHead might lead to the execution of arbitrary code or data loss.

Background

JHead is an exif jpeg header manipulation tool.

Affected Packages

Package: media-gfx/jhead
Vulnerable: < 2.84-r1
Unaffected: >= 2.84-r1
Architectures: All supported architectures


Description

Marc Merlin and John Dong reported multiple vulnerabilities in JHead:
  • A buffer overflow in the DoCommand() function when processing the cmd argument and related to potential string overflows (CVE-2008-4575).
  • An insecure creation of a temporary file (CVE-2008-4639).
  • A error when unlinking a file (CVE-2008-4640).
  • Insufficient escaping of shell metacharacters (CVE-2008-4641).


Impact

A remote attacker could possibly execute arbitrary code by enticing a user or automated system to open a file with a long filename or via unspecified vectors. It is also possible to trick a user into deleting or overwriting files.

Workaround

There is no known workaround at this time.

Resolution

All JHead users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/jhead-2.84-r1"
