Description:

The remote host is affected by the vulnerability described in GLSA-200411-01
(ppp: Remote denial of service vulnerability)


The pppd server improperly verifies header fields, making it vulnerable to
denial of service attacks.

Impact

An attacker can cause the pppd server to access memory that it isn't
allowed to, causing the server to crash. No code execution is possible with
this vulnerability, because no data is getting copied.

Workaround

There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dialup/ppp-2.4.2-r7"


Risk factor : Medium
