Fixed In Version: vim 9.0.2142
Doc Type: If docs needed, set a value
Doc Text:
A stack-based buffer overflow flaw was found in Vim. The did_set_langmap function in map.c calls sprintf to write to the error buffer that is passed down to the option callback functions. That buffer can be overflown, possibly leading to memory corruption and escalation of privileges.

Description Pedro Sampaio 2024-02-06 13:36:49 UTC 
Vim before 9.0.2142 has a stack-based buffer overflow because did_set_langmap in map.c calls sprintf to write to the error buffer that is passed down to the option callback functions.
