<p>
|
|
Multiple vulnerabilities have been found in the implimentation of protocol
|
|
H.323 contained in pwlib. Most of the vulnerabilies are in the parsing of
|
|
ASN.1 elements which would allow an attacker to use a maliciously crafted
|
|
ASN.1 element to cause unpredictable behavior in pwlib.
|
|
</p>
|
|

|
|
<impact type="high">
|
|
<p>
|
|
An attacker may cause a denial of service condition or cause a buffer
|
|
overflow that would allow arbitrary code to be executed with root
|
|
privileges.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Blocking ports 1719 and 1720 may reduce the likelihood of an attack. All
|
|
users are advised to upgrade to the latest version of the affected package.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All pwlib users are advised to upgrade to version 1.5.2-r3 or later:
|
|
</p>

<code>

# emerge sync

# emerge -pv ">=dev-libs/pwlib-1.5.2-r3"

# emerge ">=dev-libs/pwlib-1.5.2-r3"</code>
