CheckInstall multiple symlink
|checkinstall-multiple-symlink (43440)||Medium Risk|
CheckInstall could allow a local attacker to launch a symlink attack, caused by an error in the checkinstall and installwatch scripts. Certain directories are created with insecure permissions. A local attacker could exploit this vulnerability by creating a symbolic link from a temporary file to other files on the system, which would allow the attacker to overwrite arbitrary files on the system with elevated privileges.
No remedy available as of September 1, 2014.
