Two issues have been fixed in bash, the GNU Bourne-Again Shell:

  • CVE-2016-9401

    The popd builtin segfaulted when called with negative out of range offsets.

  • CVE-2019-9924

    Sylvain Beucler discovered that it was possible to call commands that contained a slash when in restricted mode (rbash) by adding them to the BASH_CMDS array.

For Debian 8 Jessie, these problems have been fixed in version 4.3-11+deb8u2.

We recommend that you upgrade your bash packages.
