Several problems were discovered in libcurl, a multi-protocol file

identifies the following problems:

CVE-2005-3185

   A vulnerability has been discovered a buffer overflow in libcurl
   that could allow the execution of arbitrary code.

CVE-2005-4077

   Stefan Esser discovered several off-by-one errors that allows
   local users to trigger a buffer overflow and cause a denial of
   service or bypass PHP security restrictions via certain URLs.

For the old stable distribution (woody) these problems have been fixed in
version 7.9.5-1woody1.

For the stable distribution (sarge) these problems have been fixed in
version 7.13.2-2sarge4.  This update also includes a bugfix against

We recommend that you upgrade your libcurl packages.

Hats off to the LibCurl programmers.

Isn't this old?  Or is there a new one?  I remember lynx and curl had a couple (really stupid) vulnerabilities a couple months ago.  It's possible that it's taken Debian this long to patch it, though, I often see them re-post really old vulnerabilities when they update their distro :)
