<title>Berkeley MPEG Tools: Multiple insecure temporary files</title>
|
|
<synopsis>
|
|
The Berkeley MPEG Tools use temporary files in various insecure ways,
|
|
potentially allowing a local user to overwrite arbitrary files.

The Berkeley MPEG Tools are a collection of utilities for
|
|
manipulating MPEG video technology, including an encoder (mpeg_encode)
|
|
and various conversion utilities.

|
|
Mike Frysinger of the Gentoo Security Team discovered that
|
|
mpeg_encode and the conversion utilities were creating temporary files
|
|
with predictable or fixed filenames. The 'test' make target of the MPEG
|
|
Tools also relied on several temporary files created insecurely.

|
<p>
|
|
A local attacker could create symbolic links in the temporary
|
|
files directory, pointing to a valid file somewhere on the filesystem.
|
|
When the utilities are executed (or 'make test' is run), this would
|
|
result in the file being overwritten with the rights of the user
|
|
running the command.

<workaround>

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

All Berkeley MPEG Tools users should upgrade to the latest

version:
