Description:
Sun has acknowledged a security issue in Solaris, which can be exploited by malicious, local users to perform certain actions with escalated privileges.
The security issue is caused due to the inetd daemon logging debug messages to "/var/tmp/inetd.log". This can be exploited to e.g. write data into another file and cause a DoS (Denial of Service) via symlink attacks.
Successful exploitation requires that debug logging is enabled.
The security issue is reported in Solaris 10 for the SPARC and x86 platforms.
Solution:
Apply patches.
SPARC platform:
Apply patch 127718-05 or later.
x86 platform:
Apply patch 127719-05 or later.
Provided and/or discovered by:
Reported by the vendor.
Changelog:
2008-04-11: Added CVE reference.
