Vulnerability Name:

CVE-2010-2450 (CCN-174837)

Assigned:2010-02-26
Published:2010-02-26
Updated:2019-11-13
Summary:The keygen.sh script in Shibboleth SP 2.0 (located in /usr/local/etc/shibboleth by default) uses OpenSSL to create a DES private key which is placed in sp-key.pm. It relies on the root umask (default 22) instead of chmoding the resulting file itself, so the generated private key is world readable by default.
