A fuzz on libpcre1 through the pcretest utility revealed an invalid memory read. Upstream says that this bug is fixed by one of the previous commit. However I’m providing as usual the stacktrace and the reproducer, so if you are not running the latest upstream release, like happen on debian/rhel based distros, you may want to check better the status of this bug.
