<title>LSAT: Insecure temporary file creation</title>
|
||
|
|
<synopsis>
|
||
|
|
LSAT insecurely creates temporary files which can lead to symlink attacks
|
||
|
|
allowing a local user to overwrite arbitrary files.

The Linux Security Auditing Tool (LSAT) is a post install security
|
||
|
|
auditor which checks many system configurations and local network
|
||
|
|
settings on the system for common security or configuration errors and
|
||
|
|
for packages that are not needed.

LSAT insecurely writes in /tmp with a predictable filename.

<p>
|

|
|
A local attacker could create symbolic links in the temporary files
|
||
|
|
directory, pointing to a valid file somewhere on the filesystem. When
|
||
|
|
the LSAT script is executed, this would result in the file being
|
||
|
|
overwritten with the rights of the user running the software, which
|
||
|
|
could be the root user.
|
||
|
|

<workaround>
|

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

All lsat users should upgrade to the latest version:
