How to fix?

Upgrade Debian:unstable vim to version 2:9.2.0858-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream vim package and not the vim package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Vim is an open source, command line text editor. Prior to 9.2.0846, set_sofo() in src/spellfile.c reuses sl_sal_first[] without resetting values left by set_sal_first(), so a crafted spell file containing an SN_SAL section before an SN_SOFO section causes under-counted mapping lists and attacker-influenced writes beyond a heap allocation. This issue is fixed in version 9.2.0846.
