TITLE:
openSUSE libxcrypt MD5 Password Hash Configuration Weakness

SECUNIA ADVISORY ID:
SA31096

VERIFY ADVISORY:
http://secunia.com/advisories/31096/

CRITICAL:
Not critical

IMPACT:
Security Bypass

WHERE:
Local system

OPERATING SYSTEM:
openSUSE 11.0
http://secunia.com/product/19180/

DESCRIPTION:
SUSE has acknowledged a weakness in libxcrypt, which results in
potentially weaker security and may allow further attacks.

The weakness is caused due to libxcrypt using the DES algorithm to
generate password hashes, although the MD5 algorithm is configured in
/etc/default/passwd.

SOLUTION:
Apply updated packages and regenerate all passwords.
