This update fixes a security issue:
By sending an unsolicited EAP packet to a vulnerable ppp client or server,
an unauthenticated remote attacker could cause memory corruption in the
pppd process, which may allow for arbitrary code execution.

Subject: [PATCH] pppd: Fix bounds check in EAP code
|
|
|
|
Given that we have just checked vallen < len, it can never be the case
|
|
that vallen >= len + sizeof(rhostname). This fixes the check so we
|
|
actually avoid overflowing the rhostname array.
