There seems to be some confusion regarding our recent gv buffer overflow
GLSA. This GLSA came on the heels of the following fake advisory, which
also reported a buffer overflow in gv[1]. That advisory contained
alleged exploit code that, in fact, contained a local DoS exploit.

The gv vulnerability reported and patched in GLSA 200408-10 is not the
same as this fictitious vulnerability. The vulnerability patched is the
same referred to in the CVE reference[2] included in the GLSA, a real
two-year old vulnerability in gv.

Please do not run the alleged exploit code listed in the fictigious gv
advisory, as it is a local DoS exploit. However, all information
contained in the GLSA is correct, and all Gentoo users should still
upgrade their gv installations to the latest available version.

This e-mail is merely meant to clarify some confusion that may have
resulted from bad information in the relevant Gentoo bug[3] and comments
on various security mailing lists. The information contained within the
GLSA is still valid, and therefore no official errata will be issued.

For more information on Gentoo security policies, please see Gentoo's
Vulnerability Policy[4].
