SILC Server and Toolkit silcd.c Symlink Arbitrary File Overwrite
Local Access Required
Loss of Integrity
SILC Server and Toolkit contains a flaw that may allow a malicious local user to overwrite arbitrary files on the system. The issue is due to the program creating temporary files insecurely. It is possible for a user to use a symlink style attack to manipulate arbitrary files, resulting in a loss of integrity.
Currently, there are no known workarounds or upgrades to correct this issue. However, Tavis Ormandy (Gentoo) has released an unofficial patch to address this vulnerability.
