Zebedee: Denial of Service vulnerability — GLSA 200509-14

A bug in Zebedee allows a remote attacker to perform a Denial of Service attack.

Package	net-misc/zebedee on all architectures
Affected versions	< 2.5.3
Unaffected versions	revision >= 2.4.1-r1 >= 2.5.3

Zebedee is an application that establishes an encrypted, compressed tunnel for TCP/IP or UDP data transfer between two systems.

"Shiraishi.M" reported that Zebedee crashes when "0" is received as the port number in the protocol option header.

By performing malformed requests a remote attacker could cause Zebedee to crash.

There is no known workaround at this time.

All Zebedee users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose net-misc/zebedee
