15 Synopsis
16 ========
17
18 A NULL pointer dereference in Openswan may allow remote attackers to
19 cause Denial of Service.
20
21 Background
22 ==========
23
24 Openswan is an implementation of IPsec for Linux.
25
26 Affected packages

43
44 Impact

48
49 Workaround
50 ==========
51
52 There is no known workaround at this time.
53
54 Resolution
55 ==========
56
57 Gentoo has discontinued support for Openswan. We recommend that users
58 unmerge Openswan:
59
60 # emerge --unmerge "net-misc/openswan"
61
62 NOTE: The Gentoo developer(s) maintaining Openswan have discontinued
63 support at this time. It may be possible that a new Gentoo developer
64 will update Openswan at a later date. Alternatives packages such as
65 Libreswan and strongSwan are currently available in Gentoo Portage.
