Description SMASH SMASH 2023-11-20 09:06:04 UTC

When getting the count for a normal mode z command, it may overflow for large counts given. So let's verify that the result can be safely stored, else abort the z command.

Impact is low, user interaction is required and a crash may not even happen.

The Vim project would like to thank Fabian Toepfer for reporting this issue which is now fixed in Vim patch 9.0.2109.

Comment 13 Martin Schreiner 2024-06-19 19:59:28 UTC

I don't think this bug is relevant anymore, as the following codestreams are all shipping Vim 9.1.0330 as of today:

SLE-12:Update
SLE-15-SP5:Update
SLE-15:Update

This CVE is also mentioned on its changelog, so the reference is not missing anywhere.
I'm closing it.

Comment 14 Martin Schreiner 2024-06-20 13:21:56 UTC

Reassigning to security.
