Fedora Project rpmdevtools and Debian devscripts TOCTOU symlink
|rpmdevtools-toctou-symlink (78230)||Medium Risk|
Fedora Project rpmdevtools and Debian devscripts could allow a local attacker to launch a symlink attack, caused by a TOCTOU race condition. The annotate-output tool creates temporary files insecurely. A local attacker could exploit this vulnerability by creating a symbolic link from a temporary file to various files on the system, which could allow the attacker to overwrite arbitrary files on the system with elevated privileges.
Apply the appropriate update for your system. See References.
