PCRE contains a buffer overflow vulnerability when processing a
|
||
|
|
character class containing a very large number of characters with
|
||
|
|
codepoints greater than 255.
|
||

<impact type="high">
|
||
|
|
<p>
|
||
|
|
A remote attacker could exploit this vulnerability by sending a
|
||
|
|
specially crafted regular expression to an application making use of
|
||
|
|
the PCRE library, which could possibly lead to the execution of
|
||
|
|
arbitrary code or a Denial of Service.

||
|

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