CVE-2016-7032

Published: 14 April 2017

sudo_noexec.so in Sudo before 1.8.15 on Linux might allow local users to bypass intended noexec command restrictions via an application that calls the (1) system or (2) popen function.

Notes

AuthorNote

I'm marking this negligible because this feature seems doomed
to failure in the general case. Any sort of memory-protection flaws
in the target process, or ability to execute system calls directly,
or programs that don't use the standard C libraries, etc. won't be
affected by this feature.
If you rely upon this feature I suggest instead seccomp2-based
filters to disable the execve() and execveat() system calls at the
kernel interface or AppArmor (or other MAC system) to restrict which
executables can be executed.
