Package : linux
CVE ID : CVE-2015-2925 CVE-2015-5257 CVE-2015-5283 CVE-2015-7613

bind-mounted into a chroot or mount namespace, a user that should
be confined to that chroot or namespace could access the whole of

Whiteheat USB serial device but presenting a smaller number of
Marcelo Ricardo Leitner discovered that creating multiple SCTP
sockets at the same time could cause a denial of service (crash)

For the oldstable distribution (wheezy), these problems have been fixed
in version 3.2.68-1+deb7u5.
For the stable distribution (jessie), these problems have been fixed in
For the unstable distribution (sid), these problems have been fixed in
version 4.2.3-1 or earlier versions.
We recommend that you upgrade your linux packages.
