security bug in Apache regarding SSI and symbolic links?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Last month I had a problem where SSI appeared to be ignoring the
SymlinkIfOwnerMatch configuration directive. I opened a bug, and eventually
discovered what appears to be a problem in the ap_directory_walk function,
where reusing cached directory information bypasses the symbolic link
check.

I think this is a security issue, not a critical one by any means, but
still a security bug. I would appreciate it if any interested parties could
possibly look at my bug:

	https://issues.apache.org/bugzilla/show_bug.cgi?id=45959

and provide some feedback on this problem and how it might be resolved. For
now, I'm tentatively considering simply bypassing the cache check, which
results in correct behavior and I don't think would be particularly costly
in terms of resources.

Thanks...
