crypto: algifaead - Revert to operating out-of-place

An attacker can leverage sudo's -R (--chroot) option to run arbitrary commands as root, even if they are not listed in the sudoers file. Sudo versions 1.9.14 to 1.9.17 inclusive are affected.

A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.

A use-after-free flaw was found in nftables cross-table in the net/netfilter/nftablesapi.c function in the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the time of table deletion, possibly leading to local privilege escalation.

A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBCTUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBCTUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.

A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system.

A vulnerability was found in cgroupreleaseagentwrite in kernel/cgroup/cgroup-v1.c in the Linux kernel. In this flaw, under certain circumstances, the cgroups v1 releaseagent feature can be used to escalate privilege and bypass namespace isolation unexpectedly.
