<title>Netpbm: Multiple temporary file issues</title>
|
|
<synopsis>
|
|
Utilities included in old Netpbm versions are vulnerable to multiple
|
|
temporary files issues, potentially allowing a local attacker to overwrite
|
|
files with the rights of the user running the utility.

Netpbm is a toolkit containing more than 200 separate utilities for
|
|
manipulation and conversion of graphic images.

|
<p>
|
|
Utilities contained in the Netpbm package prior to the 9.25 version contain
|
|
defects in temporary file handling. They create temporary files with
|
|
predictable names without checking first that the target file doesn't
|
|
already exist.
|
|
</p>
|

|
<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 a
|
|
user or a tool calls one of the affected utilities, this would result in
|
|
file overwriting with the rights of the user running the utility.
|
|
</p>
|

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

</p>

</workaround>

<resolution>
|

<p>
|
|
All Netpbm users should upgrade to an unaffected version:
|
|

<code>

# emerge sync

|
|
|
# emerge -pv ">=media-libs/netpbm-10.0"
|

# emerge ">=media-libs/netpbm-10.0"</code>
