Description Mark J. Cox 2003-10-23 13:03:08 UTC 
Georgi Guninski discovered a memory starvation denial of service
vulnerability in the ls program.  It is possible to make ls allocate a
huge amount of memory by specifing certain command line arguments.  This
vulnerability is remotely exploitable through services like wu-ftpd which
pass user arguments to ls.  The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2003-0854 to this issue.

A non-exploitable integer overflow in ls has been discovered.  It is
possible to make ls crash by specifing certain command line arguments. 
This vulnerability is remotely exploitable through services like wu-ftpd
which pass user arguments to ls.  The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2003-0853 to this issue.

RHSA-2003:310 in progress to correct these issues.
