DESCRIPTION

* CVE-2016-7097: Permissions bypass using setxattr syscall on multiple filesystems.

A logic error when inheriting access control list from a parent
directory after setting extended attribute on BTRFS, EXT2, XFS, F2FS,
HFSPLUS, Reiserfs and JFS filesystems could lead to a permission bypass.
A local attacker could use this flaw to access sensitive information.


* CVE-2017-12762: Out-of-bounds access when using Integrated Services Digital Network (ISDN) adapter.

A missing check on user input when using an ISDN adapter could lead to an
out-of-bounds access. A local attacker could use this flaw to cause a
denial-of-service or escalate privileges.


* CVE-2017-8831: Denial-of-service when using NXP SAA7164 video driver.

A missing check on user input when using NXP SAA7164 video driver could
lead to an out-of-bounds access. A local attacker could use this flaw to
cause a denial-of-service.


* CVE-2017-9984: Denial-of-service when reading DSP messages in Turtle Beach MultiSound drivers.

A logic error when receiving messages from DSP in Turtle Beach
MultiSound drivers could lead to out-of-bounds accesses. A local
attacker could use this flaw to cause a denial-of-service.


* CVE-2017-10663: Privilege escalation when mounting F2FS image.

Missing sanity-checks in Flash-Friendly File System allows out-of-bound
write operations. This could enable a malicious user to escalate privilege
when a raw F2FS image is mounted.
