Debian Security Advisory                             security@debian.org

Package        : curl and curl-ssl
Problem type   : remote exploit
Debian-specific: no

The first release of this advisory listed a wrongly compiled curl
package for i386; this has been replaced with version 6.0-1.1.1 .

The version of curl (a tool to retrieve files using ftp, gover or http)
as distributed with Debian GNU/Linux 2.2 had a bug in the error logging
code: when it created an error message it failed to check the size of
the buffer allocated for storing the message. This could be exploited by
the remote machine by returning an invalid response to a request from
curl which overflows the error buffer and trick curl into executing
arbitrary code.

Debian ships with two versions of curl: the normal curl package, and the
crypto-enabled curl-ssl package. This bug has been fixed in curl version
6.0-1.1 and curl-ssl version 6.0-1.2, with the exception being the i386
curl package which has version 6.0-1.1.1 which replaces a wrongly
compiled earlier release as noted above.

We recommend you upgrade your curl or curl-ssl package immediately.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

Debian GNU/Linux 2.1 alias slink
- --------------------------------

  Slink did not contain curl or curl-ssl.

Debian GNU/Linux 2.2 alias potato
- ---------------------------------

  Potato was released for alpha, arm, i386, m68k, powerpc and sparc. At
  this moment packages for m68k are not yet available; they will later be
  announce on http://security.debian.org/ .
