Package        : hiki
Vulnerability  : missing input sanitising
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2007-2836
Debian Bug     : 430691


Kazuhiro Nishiyama found a vulnerability in hiki, a Wiki engine written
in Ruby, which could allow a remote attacker to delete arbitary files
which are writable to the Hiki user, via a specially crafted session
parameter.

For the stable distribution (etch), this problem has been fixed in version
0.8.6-1etch1.

For the unstable distribution (sid) this problem has been fixed in version
0.8.7-1.

We recommend that you upgrade your hiki (0.8.6-1etch1) package.
