Description

Updated kernel packages fix security vulnerabilities This update is based on the upstream 4.4.30 kernel and fixes at least these security issues: The filesystem implementation in the Linux kernel through 4.8.2 preserves the setgid bit during a setxattr call, which allows local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (CVE-2016-7097). Stack-based buffer overflow in the brcmf_cfg80211_start_ap function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux kernel before 4.7.5 allows local users to cause a denial of service (system crash) or possibly have unspecified other impact via a long SSID Information Element in a command to a Netlink socket (CVE-2016-8658). The IP stack in the Linux kernel before 4.6 allows remote attackers to cause a denial of service (stack consumption and panic) or possibly have unspecified other impact by triggering use of the GRO path for packets with tunnel stacking, as demonstrated by interleaved IPv4 headers and GRE headers, a related issue to CVE-2016-7039 (CVE-2016-8666). The fix for CVE-2016-7039 added in MGASA-2016-0347 has been updated to the final version merged upstream. This update also resolves a regression where amdgpu and radeon users would not get any display when using displayport (upstream regression introduced in 4.4.21, mga#19707) For other upstream fixes in this update, read the referenced changelogs.
