[USN-3880-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 27
CVEs 4
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

It was discovered that the CIFS client implementation in the Linux kernel
did not properly handle setup negotiation during session recovery, leading
to a NULL pointer exception. An attacker could use this to create a
malicious CIFS server that caused a denial of service (client system
crash). (CVE-2018-1066)

Jann Horn discovered that the procfs file system implementation in the
Linux kernel did not properly restrict the ability to inspect the kernel
stack of an arbitrary task. A local attacker could use this to expose
sensitive information. (CVE-2018-17972)

Jann Horn discovered that the mremap() system call in the Linux kernel did
not properly flush the TLB when completing, potentially leaving access to a
physical page after it has been released to the page allocator. A local
attacker could use this to cause a denial of service (system crash), expose
sensitive information, or possibly execute arbitrary code. (CVE-2018-18281)

It was discovered that the socket implementation in the Linux kernel
contained a type confusion error that could lead to memory corruption. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2018-9568)
