Background ========== JHead is an exif jpeg header manipulation tool. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/jhead < 2.84-r1 >= 2.84-r1 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: # emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/jhead-2.84-r1" References ========== [ 1 ] CVE-2008-4575 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4575 [ 2 ] CVE-2008-4639 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4639 [ 3 ] CVE-2008-4640 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4640 [ 4 ] CVE-2008-4641 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4641 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200901-02.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
