USN-3378-1 linux, linux-aws, linux-gke, linux-raspi2, linux-snapdragon vulnerabilities

Fan Wu and Shixiong Zhao discovered a race condition between inotify events and vfs rename operations in the Linux kernel. An unprivileged local attacker could use this to cause a denial of service system crash or execute arbitrary code. CVE-2017-7533 It was discovered that the Linux kernel did n...

The vulnerability of the patch offset2lib in the Linux operating system’s kernel allows a hacker to gain access to the stack protection mechanism.

The vulnerability of patch offset2lib in Linux operating systems arises from the minimal memory range between the upper boundary of the stack and the PIE binary code segment, which is located in memory starting at 0x40000000. This occurs when the RLIMITSTACK parameter is set to RLIMINFINITY, and ...

UBUNTU-CVE-2017-1000365

The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMITSTACK/RLIMINFINITY 1/4 of the size, but does not take the argument and environment pointers into account, which allows attackers to bypass this limitation. This affects Linux Kernel version...

nfs-utils: mount.nfs fails to anticipate RLIMIT_FSIZE

The nfsaddmntent function in support/nfs/nfsmntent.c in the mount.nsf tool in nfs-utils before 1.2.4 attempts to append to the /etc/mtab file without first checking whether resource limits would interfere, which allows local users to corrupt this file via a process with a small RLIMITFSIZE value,...

glibc: Suid mount helpers fail to anticipate RLIMIT_FSIZE

The addmntent function in the GNU C Library aka glibc or libc6 2.13 and earlier does not report an error status for failed attempts to write to the /etc/mtab file, which makes it easier for local users to trigger corruption of this file, as demonstrated by writes from a process with a small...
