Hi,

The following vulnerability was published for libraw. The wording for
the CVE description from the feed is disputable, believe this should
be at most DoS.

| attacker to escalate privileges via the
| LibRaw_buffer_datastream::gets(char*, int) in

If you fix the vulnerability please also make sure to include the
