    Package        : acpid
    Vulnerability  : programming error
    Problem type   : local
    Debian-specific: no
    CVE Id         : CVE-2009-4235
    
    It was discovered that acpid, the Advanced Configuration and Power
    Interface event daemon, on the oldstable distribution (etch) creates
    its log file with weak permissions, which might expose sensible
    information or might be abused by a local user to consume all free disk
    space on the same partition of the file.
    
    
    For the oldstable distribution (etch), this problem has been fixed in
    version 1.0.4-5etch2.
    
    The stable distribution (lenny) in version 1.0.8-1lenny2 and the
    unstable distribution (sid) in version 1.0.10-5, have been updated to
    fix the weak file permissions of the log file created by older
    versions.
    
    
    We recommend that you upgrade your acpid packages.
