USN-3234-1 linux, linux-aws, linux-gke, linux-raspi2, linux-snapdragon vulnerabilities

Ralf Spenneberg discovered that the ext4 implementation in the Linux kernel did not properly validate meta block groups. An attacker with physical access could use this to specially craft an ext4 image that causes a denial of service system crash. CVE-2016-10208 It was discovered that the Linux...

USN-3234-1: Linux kernel vulnerabilities

Ralf Spenneberg discovered that the ext4 implementation in the Linux kernel did not properly validate meta block groups. An attacker with physical access could use this to specially craft an ext4 image that causes a denial of service system crash. CVE-2016-10208 It was discovered that the Linux...

PT-2017-1722

Name of the Vulnerable Software and Affected Versions OpenBSD versions 5.8 through 5.9 Description The issue allows certain local users with kern.usermount privileges to cause a denial of service, resulting in a kernel panic. This can be achieved by mounting a tmpfs with a VNOVAL in the username,...

CVE-2017-5551

The simplesetacl function in fs/posixacl.c in the Linux kernel before 4.9.6 preserves the setgid bit during a setxattr call involving a tmpfs filesystem, which allows local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions. NOT...

CVE-2017-5551

CVE-2017-5551 affects the Linux kernel; the simple_set_acl function in fs/posix_acl.c does not clear the setgid bit during a setxattr call on tmpfs, enabling a local user to gain group privileges if a setgid program exists with restricted execute permissions. This is tied to an incomplete fix of ...

CVE-2017-5551

A vulnerability was found in the Linux kernel in 'tmpfs' file system. When file permissions are modified via 'chmod' and the user is not in the owning group or capable of CAPFSETID, the setgid bit is cleared in inodechangeok. Setting a POSIX ACL via 'setxattr' sets the file permissions as well as...

PT-2017-1179

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.9.6 Description The issue is related to the simple set acl function in the Linux kernel, which has inadequate access control. This can be exploited by a local attacker to elevate privileges during the execution...
