Description Vincent Danen 2010-05-20 16:39:22 EDT
Dan Rosenberg reported a directory traversal flaw in fastjar that allows an attacker, who is able to convince a victim to extract a malicious .jar file, to overwrite arbitrary files on disk without prompting the victim.  The files to be overwritten must be writable by the user extracting the .jar file.

This issue has been assigned the name CVE-2010-0831, and it is possible that it is due to an incomplete fix for CVE-2006-3619 (bug #198912).

Upon investigation, the same problem exists in the jar archiver as provided by OpenJDK and java-1.4.2-gcj-compat.
Comment 1 Vincent Danen 2010-05-20 16:47:57 EDT
The jar program as provided by java-1.4.2-gcj-compat-devel in Red Hat Enterprise Linux 4 and 5 is also vulnerable to a similar issue as CVE-2006-3619, that was actually given the name CVE-2005-1080.  I'm not sure if MITRE will assign another CVE for this issue since the original issue received two different CVE names, despite it being the same directory traversal flaw.

I've written up a script to test if the vulnerability is present in jar and fastjar.

Comment 16 Vincent Danen 2010-06-18 16:21:26 EDT
MITRE has assigned another CVE name to this flaw (CVE-2010-2322) with the following descriptions:

Name: CVE-2010-0831

Directory traversal vulnerability in the extract_jar function in
jartool.c in FastJar 0.98 allows remote attackers to create or
overwrite arbitrary files via a .. (dot dot) in a non-initial pathname
component in a filename within a .jar archive, a related issue to
CVE-2005-1080.  NOTE: this vulnerability exists because of an
incomplete fix for CVE-2006-3619.

Name: CVE-2010-2322

Absolute path traversal vulnerability in the extract_jar function in
jartool.c in FastJar 0.98 allows remote attackers to create or
overwrite arbitrary files via a full pathname for a file within a .jar
archive, a related issue to CVE-2010-0831.  NOTE: this vulnerability
exists because of an incomplete fix for CVE-2006-3619.
Comment 17 Vincent Danen 2010-06-21 11:59:14 EDT
A separate bug has been filed for jar (bug #606442, CVE-2005-1080).  This bug is for fastjar in gcc only.
