Package        : tomcat-native
CVE ID         : CVE-2017-15698

Jonas Klempel reported that tomcat-native, a library giving Tomcat
access to the Apache Portable Runtime (APR) library's network connection
(socket) implementation and random-number generator, does not properly
handle fields longer than 127 bytes when parsing the AIA-Extension field
of a client certificate. If OCSP checks are used, this could result in
client certificates that should have been rejected to be accepted.

For the oldstable distribution (jessie), this problem has been fixed
in version 1.1.32~repack-2+deb8u1.

For the stable distribution (stretch), this problem has been fixed in
version 1.2.12-2+deb9u1.

We recommend that you upgrade your tomcat-native packages.
