Description Ville Skyttä 2008-03-07 14:44:46 EST

curl/interface.c in the cURL library (aka libcurl) in PHP 5.2.4 and 5.2.5 allows
context-dependent attackers to bypass safe_mode and open_basedir restrictions

NVD statement regarding this flaw and php packages shipped in Red Hat Enterprise
Linux and Red Hat Application Stack is available on the url also mentioned in
the initial comment - http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-4850:

  Official Statement from Red Hat (1/25/2008)
  We do not consider these to be security issues. For more details see
  and http:www.php.netsecurity-note.php

There is currently not plan to backport a fix for this issue to Red Hat
Enterprise Linux and Red Hat Application Stack php packages.

For Fedora, this issue will most likely be fixed once next upstream release -
5.2.6 (not yet released upstream) - is uploaded to Fedora repositories.
Comment 2 Tomas Hoger 2008-07-25 04:21:42 EDT
Fedora packages are already updated to upstream version 5.2.6.
