R javareconf symlink
|r-javareconf-symlink (44736)||Medium Risk|
R could allow a local attacker to launch a symlink attack, caused by an error in the javareconf script. Temporary files 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.
Upgrade to the latest version of R (version 2.8.0 or later), available from the R Project Web site. See References.
