{"schemaVersion":3,"id":"MGASA-2017-0345","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Updated kernel packages fix security vulnerabilities\n\nThis kernel update is based on upstream 4.4.88 and fixes at least the\nfollowing security issues:\n\nnet/xfrm/xfrm_policy.c in the Linux kernel through 4.12.3, when\nCONFIG_XFRM_MIGRATE is enabled, does not ensure that the dir value of\nxfrm_userpolicy_id is XFRM_POLICY_MAX or less, which allows local users\nto cause a denial of service (out-of-bounds access) or possibly have\nunspecified other impact via an XFRM_MSG_MIGRATE xfrm Netlink message\n(CVE-2017-11600).\n\nThe xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen\nmight allow local OS guest users to corrupt block device data streams\nand consequently obtain sensitive memory information, cause a denial of\nservice, or gain host OS privileges by leveraging incorrect block IO\nmerge-ability calculation (CVE-2017-12134 / XSA-229).\n\nThe XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h in the Linux kernel\nbefore 4.13.2 does not verify that a filesystem has a realtime device,\nwhich allows local users to cause a denial of service (NULL pointer\ndereference and OOPS) via vectors related to setting an RHINHERIT flag\non a directory (CVE-2017-14340).\n\nThe native Bluetooth stack in the Linux Kernel (BlueZ), starting at the\nLinux kernel version 3.3-rc1 and up to and including 4.13.1, are vulnerable\nto a stack overflow vulnerability in the processing of L2CAP configuration\nresponses resulting in Remote code execution in kernel space\n(CVE-2017-1000251).\n\nFor other upstream fixes in this update, read the referenced changelogs.","dates":{"published":"2017-09-16T08:24:57.000Z","modified":"2026-04-16T06:23:25.786Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"mageia","product":"kernel","name":"kernel","label":"kernel","ecosystem":"Mageia","cpePart":null,"purl":"pkg:rpm/mageia/kernel","purlType":"rpm","versions":[{"text":"<
