Title:
[REGRESSION] Task based libapparmor getcon functions don't always NUL-
terminate con strings properly
Status in AppArmor Linux application security framework:
Fix Released
Status in “apparmor” package in Ubuntu:
Fix Released
Bug description:
Starting with upstream revision 2125 and Ubuntu package 2.8.0-0ubuntu25,
the task based libapparmor getcon functions changed behavior on how they
handled NULL mode strings.
Old behavior:
$ gcc -Wall -pedantic -o getcon getcon.c -lapparmor
$ echo "profile getcon { file, }" | sudo apparmor_parser -qr
$ aa-exec -p getcon -- ./getcon
con = [getcon]
New behavior:
$ gcc -Wall -pedantic -o getcon getcon.c -lapparmor
$ echo "profile getcon { file, }" | sudo apparmor_parser -qr
$ aa-exec -p getcon -- ./getcon
con = [getcon (enforce)]
The con string is not being NUL-terminated before the mode string when
the mode pointer is NULL.
