Description

This update for libdb-4_5 fixes the following issues :

  • A DB_CONFIG file in the current working directory allowed local users to obtain sensitive information via a symlink attack involving a setgid or setuid application using libdb-4_8. (bsc#1043886)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
