Comment 1 Charles Arnold 2023-08-28 17:18:08 UTC

The recommended fix given in redhat bug,

https://bugzilla.redhat.com/show_bug.cgi?id=2234984

is already in our older distros and is part of the newer distro tarballs.
See bsc#1023079 (CVE-2016-9578) for the patch for the older distros.


Fix is part of the tarball:
SLE-15-SP1/SP2/SP3/SP4/SP5

Patch CVE-2016-9578-remote-dos-via-crafted-message.patch already included for:
SLE-12-SP1/SP2/SP3/SP4/SP5, SLE11-SP4

I don't think there is anything more to be done.

Comment 2 Carlos López 2023-08-30 13:11:01 UTC

Closing this since it was already fixed.
