Description:
This update contains a kernel live patch for the 3.12.43-52.6 SUSE Linux Enterprise Server 12 Kernel, fixing following security issues.
- CVE-2015-5364/CVE-2015-5366: Two denial of service attacks via a flood of UDP packets with invalid checksums were fixed that could be used by remote attackers to delay execution. (bsc#939276)
- CVE-2015-1805: The (1) pipe_read and (2) pipe_write implementations in fs/pipe.c in the Linux kernel did not properly consider the side effects of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls, which allowed local users to cause a denial of service (system crash) or possibly gain privileges via a crafted application, aka an "I/O vector array overrun." (bsc#939270)
- CVE-2015-4700: A BPF Jit optimization flaw could allow local users to panic the kernel. (bsc#939273)
