High [CVE-2024-21626] runc container breakout through process.cwd trickery and leaked fds
runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. In runc 1.1.11 and earlier, due to an internal file descriptor leak, an attacker could cause a newly-spawned container process (from runc exec) to have a working directory in the host filesystem namespace, allowing for a container escape by giving access to the host filesystem ("attack 2"). The same attack could be used by a malicious image to allow a container process to gain access to the host filesystem through runc run ("attack 1"). Variants of attacks 1 and 2 could be also be used to overwrite semi-arbitrary host binaries, allowing for complete container escapes ("attack 3a" and "attack 3b"). runc 1.1.12 includes patches for this issue. While a user performs `O_CLOEXEC` all file descriptors before executing the container code, the file descriptor is open when performing `setcwd(2)`, which means that the reference can be kept alive in the container by configuring the working directory to be a path resolved through the file descriptor. The non-dumpable bit is unset after `execve`, meaning there are multiple ways to attack this other than bad configurations. The only way to defend against it entirely is to close all unneeded file descriptors.
High [CVE-2023-52355] Libtiff: tiffrasterscanlinesize64 produce too-big size and could cause oom
An out-of-memory flaw was found in libtiff that could be triggered by passing a crafted tiff file to the TIFFRasterScanlineSize64() API. This flaw allows a remote attacker to cause a denial of service via a crafted input with a size smaller than 379 KB. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 9; Red Hat AI Inference Server 3.2; Red Hat Discovery 2; and 1 more. Affected products named by the advisory: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9.6 Extended Update Support.
High [CVE-2023-4692] Grub2: out-of-bounds write at fs/ntfs.c may lead to unsigned code execution
An out-of-bounds write flaw was found in grub2's NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub's heap metadata corruption. In some circumstances, the attack may also corrupt the UEFI firmware heap metadata. As a result, arbitrary code execution and secure boot protection bypass may be achieved. Affected products named by the advisory: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat Enterprise Linux 7.
High [CVE-2023-4911] Glibc: buffer overflow in ld.so leading to privilege escalation
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges. Affected products named by the advisory: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 8.6 Extended Update Support; Red Hat Enterprise Linux 9; Red Hat Enterprise Linux 9.0 Extended Update Support; and 1 more. Affected products named by the advisory: Red Hat Virtualization 4 for Red Hat Enterprise Linux 8.
High [CVE-2023-0597 +1] Kernel: x86/mm: a per-cpu entry area leak was identified through the init_cea_offsets function when prefetchnta and prefetcht2 instructions being used for the per-cpu entry area mapping to the user space
A possible unauthorized memory access flaw was found in the Linux kernel's cpu_entry_area mapping of X86 CPU data to memory, where a user may guess the location of exception stacks or other important data. Based on the previous CVE-2023-0597, the 'Randomize per-cpu entry area' feature was implemented in /arch/x86/mm/cpu_entry_area.c, which works through the init_cea_offsets() function when KASLR is enabled. However, despite this feature, there is still a risk of per-cpu entry area leaks. This issue could allow a local user to gain access to some important data with memory in an expected location and potentially escalate their privileges on the system. Affected products named by the advisory: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9.
High [CVE-2013-0335] Openstack nova: vnc proxy can connect to the wrong vm
OpenStack Compute (Nova) Grizzly, Folsom (2012.2), and Essex (2012.1) allows remote authenticated users to gain access to a VM in opportunistic circumstances by using the VNC token for a deleted VM that was bound to the same VNC port. Affected product named by the advisory: OpenStack Folsom for RHEL 6.
