Topic

Updated w3c-libwww packages that fix a security issue and a bug are now
available.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

Description

w3c-libwww is a general-purpose web library.

Several buffer overflow flaws in w3c-libwww were found. If a client
application that uses w3c-libwww connected to a malicious HTTP server, it
could trigger an out of bounds memory access, causing the client
application to crash (CVE-2005-3183).

This updated version of w3c-libwww also fixes an issue when computing MD5
sums on a 64 bit machine.

Users of w3c-libwww should upgrade to these updated packages, which contain
backported patches to correct these issues.
