Debian LTS: DLA-3919-1: libapache-mod-jk Security Advisory Updates
Summary
An issue with incorrect default permissions could have allowed local
users to view and modify shared memory containing mod_jk's
configuration, which may have potentially led to information
disclosure and/or a denial of service attack.
For Debian 11 bullseye, this problem has been fixed in version
1:1.2.48-1+deb11u2.
We recommend that you upgrade your libapache-mod-jk packages.
