Out-of-bounds Read in GitHub repository vim/vim prior to 9.0.0212.
An out-of-bounds read vulnerability was found in Vim in the check_vim9_unlet function in the vim9cmds.c file. This issue occurs because of invalid memory access when compiling the unlet command when a specially crafted input is processed. This flaw allows an attacker who can trick a user into opening a specially crafted file into triggering the out-of-bounds read, causing the application to crash, possibly executing code and corrupting memory.
Отчет
Red Hat Product Security has rated this issue as having a Low security impact because the user has to run an untrusted file IN SCRIPT MODE. Someone who is running untrusted files in script mode is equivalent to someone just taking a random python script and running it. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/ and Red Hat Enterprise Linux Life Cycle & Updates Policy: https://access.redhat.com/support/policy/updates/errata/.
Меры по смягчению последствий
Do not run untrusted vim scripts as it's not recommended.
