Debian DLA-1392-1 : linux security update

high Nessus Plugin ID 110314

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
