This update fixes the CVEs described below.
CVE-2013-7446
Dmitry Vyukov discovered that a particular sequence of valid operations on local (AF_UNIX) sockets can result in a use-after-free.
This may be used to cause a denial of service (crash) or possibly for privilege escalation.
CVE-2015-7799
郭永刚 discovered that a user granted access to /dev/ppp can cause a denial of service (crash) by passing invalid parameters to the PPPIOCSMAXCID ioctl. This also applies to ISDN PPP device nodes.
CVE-2015-7833
Sergej Schumilo, Hendrik Schwartke and Ralf Spenneberg discovered a flaw in the processing of certain USB device descriptors in the usbvision driver. An attacker with physical access to the system can use this flaw to crash the system.
CVE-2015-7990
It was discovered that the fix for CVE-2015-6937 was incomplete. A race condition when sending a message on unbound socket can still cause a NULL pointer dereference. A remote attacker might be able to cause a denial of service (crash) by sending a crafted packet.
CVE-2015-8324
‘Valintinr’ reported that an attempt to mount a corrupted ext4 filesystem may result in a kernel panic. A user permitted to mount filesystems could use this flaw to crash the system.
For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze17. We recommend that you upgrade your linux-2.6 packages.
For the oldstable (wheezy) and stable (jessie) distributions, CVE-2015-7833, CVE-2015-7990 and CVE-2015-8324 have been fixed and the other issues will be fixed soon.
