LHa is a console-based program for packing and unpacking LHarc archives.

<p>
|
|
The command line argument as well as the archive parsing code of LHa lack
|
|
sufficient bounds checking. Furthermore, a shell meta character command
|
|
execution vulnerability exists in LHa, since it does no proper filtering on
|
|
directory names.

|

|
<impact type="normal">
|
|
<p>
|
|
Using a specially crafted command line argument or archive, an attacker can
|
|
cause a buffer overflow and could possibly run arbitrary code. The shell
|
|
meta character command execution could lead to the execution of arbitrary
|
|
commands by an attacker using directories containing shell meta characters
|
|
in their names.
|

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

</workaround>

<resolution>
|
|
<p>
|
|
All LHa users should upgrade to the latest stable version:
|

<code>

# emerge sync

# emerge -pv ">=app-arch/lha-114i-r4"

# emerge ">=app-arch/lha-114i-r4"</code>
