DescriptionCVE.org

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.

AnalysisAI

Vim crashes with an out-of-bounds read when opening a maliciously crafted file encrypted with the xchacha20poly1305 cipher (VimCrypt~04! or VimCrypt~05!) whose body is shorter than a libsodium secretstream header. …

Vulnerability AssessmentAI

Exploitation Two non-default conditions must both be true: (1) Vim must be compiled with the +sodium feature linking against libsodium - many distribution builds omit this; (2) the user must open a file using VimCrypt~04! … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 5.5 (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) correctly frames this as a local, user-interaction-dependent denial of service. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts a VimCrypt~04!-prefixed file with a valid 36-byte header (12-byte magic, 16-byte salt, 8-byte seed) followed by a body shorter than the 24-byte libsodium secretstream header - as small as 8 bytes - and delivers it to a target user via email attachment, shared filesystem, or download. When the user opens the file in a +sodium-enabled Vim build, the unsigned length underflow triggers an out-of-bounds read in libsodium's pull function, immediately crashing Vim and losing any unsaved work in the session. …
Remediation Upgrade Vim to version 9.2.0671 or later; the patch is confirmed released via GitHub at https://github.com/vim/vim/releases/tag/v9.2.0671 and the fix commit is https://github.com/vim/vim/commit/c8777cec25dcfae89c42e9aff51af61f71c5745f. … Detailed patch versions, workarounds, and compensating controls in full report.
