    Ivan Shmakov discovered that the htmlscrubber component of ikwiki, a wiki compiler, performs insufficient input sanitization on data:image/svg+xml URIs. As these can contain script code this can be used by an attacker to conduct cross-site scripting attacks.

    Debian GNU/Linux 5.0 alias lenny
    - --------------------------------
    
    Debian (stable)
    - ---------------
    
    Stable updates are available for alpha, amd64, arm, armel, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
    
    Source archives:
    
      http://security.debian.org/pool/updates/main/i/ikiwiki/ikiwiki_2.53.5.dsc
