UUDeview is a program which is used to transmit binary files over the
|
|
Internet in a text-only format. It is commonly used for email and Usenet
|
|
attachments. It supports multiple encoding formats, including Base64,
|
|
BinHex and UUEncoding.

<p>
|
|
By decoding a MIME archive with excessively long strings for various
|
|
parameters, it is possible to crash UUDeview, or cause it to execute
|
|
arbitrary code.
|
|
</p>
|
|
<p>
|
|
This vulnerability was originally reported by iDEFENSE as part of a WinZip
|
|
advisory [ Reference: 1 ].

<impact type="normal">
|
|
<p>
|
|
An attacker could create a specially-crafted MIME file and send it via
|
|
email. When recipient decodes the file, UUDeview may execute arbitrary code
|
|
which is embedded in the MIME file, thus granting the attacker access to
|
|
the recipient's account.

|

|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time. As a result, a software upgrade
|
|
is required and users should upgrade to uudeview 0.5.20.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All users should upgrade to uudeview 0.5.20:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
# emerge -pv ">=app-text/uudeview-0.5.20"
|
