Description Jan Lieskovsky 2013-04-03 08:14:24 EDT
It was reported that the XML files parser of ModSecurity, a security module for the Apache HTTP Server, was vulnerable to XML External Entity attacks. A remote attacker could provide a specially-crafted XML file that, when processed might lead to local files disclosure or, potentially, excessive resources (memory, CPU) consumption.

Comment 1 Jan Lieskovsky 2013-04-03 08:16:36 EDT
This issue affects the versions of the mod_security package, as shipped with Fedora release of 17, 18, and Fedora EPEL-6. Please schedule an update.

This issue (possibly [*]) affects the version of the mod_security package, as shipped with Fedora EPEL-5. Please schedule an update.

[*] Possibly because particular upstream patch [4] wouldn't be applicable directly without backport. But basically it's applicable to this version too.

> Update are mostly done, note that F19 is also affected.

Thank you for those, Athmane. Ad Fedora-19 sure / it's possible. But since it has not been officially released yet, we aren't referring to it (it's kinda automa[t,g]ically expected that version to be updated too though).

Thank you for making those again.

Jan.
