Description
This security bulletin contains information about 3 vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2026-57452)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to out-of-bounds read in crypt_sodium_buffer_decode() when parsing a crafted libsodium-encrypted file. A remote attacker can trick the victim into opening a crafted file and entering a key to cause a denial of service.
Only instances built with the +sodium feature are vulnerable, and the issue affects files using the VimCrypt~04! or VimCrypt~05! encryption method.
2) Out-of-bounds write (CVE-ID: CVE-2026-57455)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to out-of-bounds write in the single-byte branch of spell_soundfold_sofo() in src/spell.c when processing an over-long word through SOFO sound-folding. A local user can supply a specially crafted over-long word to cause a denial of service.
The vulnerable path is only reached under a non-multibyte 8-bit encoding such as latin1, with spell checking enabled for a language that uses a SOFO sound-folding table.
3) Code Injection (CVE-ID: CVE-2026-57456)
CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to improper control of code generation in Python omni-completion docstring handling in runtime/autoload/python3complete.vim and pythoncomplete.vim when processing a hostile Python buffer during omni-completion. A remote attacker can craft a malicious docstring and convince a user to trigger Python omni-completion to execute arbitrary code.
User interaction is required to open or edit a hostile Python buffer and trigger Python omni-completion. Only builds with +python3 or +python support are affected.
