The Standard security setting for Mandrake-Security package (msec) in Mandrake 8.2 installs home directories with world-readable permissions, which could allow local users to read other user's files.
SilverCity before 0.9.5-r1 installs (1) cgi-styler-form.py, (2) cgi-styler.py, and (3) source2html.py with read and write world permissions, which allows local users to execute arbitrary code.
Skype 0.92.0.12 and 1.0.0.1 for Linux, and possibly other versions, creates the /usr/share/skype/lang directory with world-writable permissions, which allows local users to modify language files and possibly conduct social engineering or other attacks.
dnskeygen in BIND 8.2.4 and earlier, and dnssec-keygen in BIND 9.1.2 and earlier, set insecure permissions for a HMAC-MD5 shared secret key file used for DNS Transactional Signatures (TSIG), which allows attackers to obtain the keys and perform dynamic DNS updates.
The default permissions of /dev/kmem in Linux versions before 2.0.36 allows IP spoofing.
