CVE-2010-2450: Debian Linux

High severity, CVSS 7.5. EPSS: 1.2% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 8.0 only; version 9.0 only
• Shibboleth Service Provider: version 2.0 only
