Mgetty: Insecure temporary file usage Mgetty uses temporary files in an insecure manner, allowing for symlink attacks. mgetty December 06, 2008 December 23, 2008: 02 235806 local 1.1.36-r3 1.1.36-r3

Mgetty is a set of fax and voice modem programs.

Dmitry E. Oboukhov reported that the "spooldir" directory in fax/faxspool.in is created in an insecure manner.

A local attacker could exploit this vulnerability to overwrite arbitrary files with the privileges of the user running the application.

There is no known workaround at this time.

All Mgetty users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/mgetty-1.1.36-r3"
