<title>ncompress: Buffer overflow</title>
|
|
<synopsis>
|
|
compress and uncompress, which could be used by daemon programs, contain a
|
|
buffer overflow that could lead to remote execution of arbitrary code with
|
|
the rights of the daemon process.

|
|
ncompress is a utility handling compression and decompression of
|
|
Lempel-Ziv archives, compatible with the original *nix compress and
|
|
uncompress utilities (.Z extensions).

<description>
|
|
<p>
|
|
compress and uncompress do not properly check bounds on command line
|
|
options, including the filename. Large parameters would trigger a
|
|
buffer overflow.

|

<impact type="normal">
|
|
<p>
|
|
By supplying a carefully crafted filename or other option, an attacker
|
|
could execute arbitrary code on the system. A local attacker could only
|
|
execute code with his own rights, but since compress and uncompress are
|
|
called by various daemon programs, this might also allow a remote
|
|
attacker to execute code with the rights of the daemon making use of
|
|
ncompress.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All ncompress users should upgrade to the latest version:

# emerge -pv ">=app-arch/ncompress-4.2.4-r1"
