<title>MIT krb5: Insecure temporary file use in send-pr.sh</title>
|
|
<synopsis>
|
|
The send-pr.sh script, included in the mit-krb5 package, is vulnerable to
|
|
symlink attacks, potentially allowing a local user to overwrite arbitrary
|
|
files with the rights of the user running the utility.

The send-pr.sh script creates temporary files in world-writeable
|
|
directories with predictable names.

<impact type="normal">
|
|
<p>
|
|
A local attacker could create symbolic links in the temporary files
|
|
directory, pointing to a valid file somewhere on the filesystem. When
|
|
send-pr.sh is called, this would result in the file being overwritten
|
|
with the rights of the user running the utility, which could be the
|
|
root user.

<workaround>

<p>
|
|
There is no known workaround at this time.

All MIT krb5 users should upgrade to the latest version:

<code>

# emerge sync

# emerge -pv ">=app-crypt/mit-krb5-1.3.4-r1"

# emerge ">=app-crypt/mit-krb5-1.3.4-r1"</code>
