Debian: DSA-4315-1 High Severity: Wireshark Denial Of Service Risk

Multiple vulnerabilities have been discovered in Wireshark, a network
protocol analyzer which could result in denial of service or the
execution of arbitrary code.

For the stable distribution (stretch), these problems have been fixed in
version 2.6.3-1~deb9u1. This update upgrades Wireshark to the 2.6.x
release branch, future security upgrades will be based on this series.

We recommend that you upgrade your wireshark packages.
