An update that solves three vulnerabilities and has one security fix can now be installed.
Description:
This update for the Linux Kernel 3.12.74-60_64_40 fixes several issues.
The following security bugs were fixed:
- CVE-2017-7533: A bug in inotify code allowed local users to escalate privilege (bsc#1050751).
- CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel is too late in checking whether an overwrite of an skb data structure may occur, which allowed local users to cause a denial of service (system crash) via crafted system calls (bsc#1042892).
- CVE-2017-8890: The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bsc#1038564).
The following non-security bug was fixed:
- A SUSE Linux Enterprise specific regression in tearing down network namespaces was fixed (bsc#1044878)
