Description Tomas Hoger 2009-04-07 10:59:23 UTC 
PHP 5.2.9 upstream release notes mention following security fix:

  Fixed a crash on extract in zip when files or directories entry names
  contain a relative path. (Pierre)

  http://www.php.net/releases/5_2_9.php

Upstream commit:
http://cvs.php.net/viewvc.cgi/php-src/ext/zip/php_zip.c?r1=1.1.2.48&r2=1.1.2.49

Note: This fix is related to CVE-2008-5658, as the checking was only introduced as part of that patch.

Just noting that CVE-2008-5658 is bug 474824.
Comment 2 Tomas Hoger 2009-04-09 07:37:36 UTC 
CVE-2009-1272:
The php_zip_make_relative_path function in php_zip.c in PHP 5.2.x
before 5.2.9 allows context-dependent attackers to cause a denial of
service (crash) via a ZIP file that contains filenames with relative
paths, which is not properly handled during extraction.
Comment 3 Tomas Hoger 2009-06-16 07:05:31 UTC 
Proper fix for CVE-2008-5658 was used in Red Hat Applications Stacks v2 updates.  PHP packages in Red Hat Enterprise Linux 2.1, 3, 4, and 5, and Red Hat Applications Stacks v1 were not affected by this flaw.

All Fedora versions are updated to 5.2.9 now.
