Alpine: gvim, multiple vim packages, xxd: security update to 9.2.0567-r0
medium Tenable Cloud Security Plugin ID 443107
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Vim is an open source, command line text editor. Prior to version 9.2.0565, the update_snapshot() function
in src/terminal.c copies the visible terminal screen into the scrollback buffer when a snapshot is taken.
For each screen cell it walks the cell's chars[] array with no upper bound, stopping only when it
encounters a NUL terminator. When a cell legitimately fills all VTERM_MAX_CHARS_PER_CELL (6) slots — a
base character plus five combining marks — the bundled libvterm returns the array without a terminating
NUL, so the loop reads past the fixed six-element array and appends the out-of-bounds values to a buffer
reserved for only six characters. A program whose output is rendered inside a :terminal window can trigger
this with a short byte sequence and no Vim scripting, leading to a crash. This issue has been patched in
version 9.2.0565. (CVE-2026-52859)
Solution
Update the gvim library and its related packages to version 9.2.0567-r0 or later.See Also
