Vulnerability Description
Vim is an open source, command line text editor. Prior to 9.2.0841, prop_add_one() in src/textprop.c uses the proplen value from get_text_props() to increment a uint16_t property count beyond 0xffff, wrapping the count to zero and copying existing text-property records into a heap allocation sized for none of them. This issue is fixed in version 9.2.0841.
