Description Mark J. Cox 2004-04-21 07:40:37 EDT
Ulf Härnhammar discovered two stack buffer overflows and two directory
traversal flaws in LHA.  An attacker could exploit the buffer
overflows by creating a carefully crafted LHA archive in such a way
that arbitrary code would be executed when the archive is tested or
extracted by a victim.  CAN-2004-0234.  An attacker could exploit the
directory traversal issues to create files as the victim outside of
the expected directory.  CAN-2004-0235.

This issue is embargoed until April 29th 2004.

Comment 1 Mark J. Cox 2004-05-02 06:50:30 EDT
removing embargo
Comment 2 Leonard den Ottolander 2004-05-11 08:00:36 EDT
Mark, why don't you propagate these bugs to Fedora Core as well? I've
been mentioning this before, obviously without result.

If you are not responsible for Fedora Core security, then who is?
Comment 3 Mark J. Cox 2004-05-11 08:06:07 EDT
Yes; I opened about 10 security bugs into FC1 and FC2 earlier today
for tracking and updated our process document so we do so in the
future.  I didn't open one for lha since 1.14i-12.1 was built into
10-updates-candidate on May05 and will be available very soon.
Comment 4 Leonard den Ottolander 2004-05-11 08:17:29 EDT
Not opening a bug report because an update will be available soon is
not very transparent. Had I seen one I wouldn't have opened bug 123019...
Comment 5 Mark J. Cox 2004-05-26 03:46:03 EDT
An errata has been issued which should help the problem 
described in this bug report. This report is therefore being 
closed with a resolution of ERRATA. For more information
