Debian Security Advisory 1364-2 – Several vulnerabilities have been discovered in the vim editor. Ulf Harnhammar discovered that a format string flaw in helptags_one() from src/ex_cmds.c (triggered through the “helptags” command) can lead to the execution of arbitrary code. Editors often provide a way to embed editor configuration commands (aka modelines) which are executed once a file is opened. Harmful commands are filtered by a sandbox mechanism. It was discovered that function calls to writefile(), feedkeys() and system() were not filtered, allowing shell command execution with a carefully crafted file opened in vim. This updated advisory repairs issues with missing files in the packages for the oldstable distribution (sarge) for the alpha, mips, and mipsel architectures.
