vim - several vulnerabilities

Several vulnerabilities have been discovered in the vim editor. The Common
Vulnerabilities and Exposures project identifies the following problems:

• CVE-2007-2953
  Ulf Härnhammar 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.
• CVE-2007-2438
  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.

For the oldstable distribution (sarge) these problems have been fixed in
version 6.3-071+1sarge2. Sarge is not affected by CVE-2007-2438.

For the stable distribution (etch) these problems have been fixed
in version 7.0-122+1etch3.

For the unstable distribution (sid) these problems have been fixed in
version 7.1-056+1.

We recommend that you upgrade your vim packages.
