PACKAGE : mc
SUMMARY : Buffer overflow vulnerability
DATE : 2004-03-31 15:03:00
ID : CLA-2004:833
RELEVANT
RELEASES : 8, 9

DESCRIPTION
Midnight Commander (MC) is a visual shell and a file manager for text
consoles.
This update fixes a buffer overflow vulnerability[1] in the code that
handles symlinks in the virtual filesystem module. An attacker could
create a specially crafted archive (like a .tar.gz or a cpio file)
containing symlinks that when opened by an mc user would trigger the
execution of arbitrary code with its privileges.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2003-1023 to this issue[2].
SOLUTION
All users of the mc package should upgrade.
