Package : linux
Version : 3.2.102-1
CVE ID : CVE-2018-1093 CVE-2018-1130 CVE-2018-8897 CVE-2018-10940
Debian Bug : 898100
Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service.
CVE-2018-1093
Wen Xu reported that a crafted ext4 filesystem image could trigger
an out-of-bounds read in the ext4_valid_block_bitmap() function. A
local user able to mount arbitrary filesystems could use this for
denial of service.
CVE-2018-1130
The syzbot software found that the DCCP implementation of
sendmsg() does not check the socket state, potentially leading
to a null pointer dereference. A local user could use this to
cause a denial of service (crash).
CVE-2018-8897
Nick Peterson of Everdox Tech LLC discovered that #DB exceptions
that are deferred by MOV SS or POP SS are not properly handled,
allowing an unprivileged user to crash the kernel and cause a
denial of service.
CVE-2018-10940
Dan Carpenter reported that the cdrom driver does not correctly
validate the parameter to the CDROM_MEDIA_CHANGED ioctl. A user
with access to a cdrom device could use this to cause a denial of
service (crash).
For Debian 7 "Wheezy", these problems have been fixed in version
3.2.102-1. This version also includes bug fixes from upstream version
3.2.102, including a fix for a regression in the SCTP implementation
in version 3.2.101.
We recommend that you upgrade your linux packages.
