Description

Vim is an open source, command line text editor. Prior to 9.2.0671, when Vim opens a file encrypted with the VimCrypt~04! or VimCrypt~05! method (xchacha20poly1305, requires the +sodium feature) whose body is shorter than a single libsodium secretstream header, an unsigned length calculation underflows and a subsequent decryption call reads far past the end of the input buffer, crashing Vim. This vulnerability is fixed in 9.2.0671.
