<description>
|
|
<p>
|
|
sharutils contains two buffer overflows. Ulf Harnhammar discovered a
|
|
buffer overflow in shar.c, where the length of data returned by the wc
|
|
command is not checked. Florian Schilhabel discovered another buffer
|
|
overflow in unshar.c.
|
|

|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
An attacker could exploit these vulnerabilities to execute arbitrary
|
|
code as the user running one of the sharutils programs.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All sharutils users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
|
|
# emerge -pv ">=app-arch/sharutils-4.2.1-r10"
|
|
# emerge ">=app-arch/sharutils-4.2.1-r10"</code>
