RHSA-2020:5437-Security Advisory

Description

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): kernel: metadata validator in XFS may cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt (CVE-2020-14385) kernel: The flow_dissector feature allows device tracking (CVE-2019-18282) kernel: Buffer over-read in crypto_authenc_extractkeys() when a payload longer than 4 bytes is not aligned. (CVE-2020-10769) kernel: buffer uses out of index in ext3/4 filesystem (CVE-2020-14314) kernel: umask not applied on filesystem without ACL support (CVE-2020-24394) kernel: TOCTOU mismatch in the NFS client code (CVE-2020-25212) kernel: improper input validation in ppp_cp_parse_cr function leads to memory corruption and read overflow (CVE-2020-25643) kernel: metadata validator in XFS may cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt (CVE-2020-14385) kernel: The flow_dissector feature allows device tracking (CVE-2019-18282) kernel: Buffer over-read in crypto_authenc_extractkeys() when a payload longer than 4 bytes is not aligned.
