Apptainer is an open source container platform for Linux

CVE-2023-30549 7.8 - High - April 25, 2023

Apptainer is an open source container platform for Linux. There is an ext4 use-after-free flaw that is exploitable through versions of Apptainer < 1.1.0, installations that include apptainer-suid < 1.1.8, and all versions of Singularity in their default configurations on older operating systems where that CVE has not been patched. That includes Red Hat Enterprise Linux 7, Debian 10 buster (unless the linux-5.10 package is installed), Ubuntu 18.04 bionic and Ubuntu 20.04 focal. Use-after-free flaws in the kernel can be used to attack the kernel for denial of service and potentially for privilege escalation. Apptainer 1.1.8 includes a patch that by default disables mounting of extfs filesystem types in setuid-root mode, while continuing to allow mounting of extfs filesystems in non-setuid "rootless" mode using fuse2fs. Some workarounds are possible. Either do not install apptainer-suid (for versions 1.1.0 through 1.1.7) or set `allow setuid = no` in apptainer.conf (or singularity.conf for singularity versions). This requires having unprivileged user namespaces enabled and except for apptainer 1.1.x versions will disallow mounting of sif files, extfs files, and squashfs files in addition to other, less significant impacts. (Encrypted sif files are also not supported unprivileged in apptainer 1.1.x.). Alternatively, use the `limit containers` options in apptainer.conf/singularity.conf to limit sif files to trusted users, groups, and/or paths, and set `allow container extfs = no` to disallow mounting of extfs overlay files. The latter option by itself does not disallow mounting of extfs overlay partitions inside SIF files, so that's why the former options are also needed.

Dangling pointer

A flaw was found in the Linux kernel's netdevsim device driver, within the scheduling of events

CVE-2023-2019 4.4 - Medium - April 24, 2023

Improper Initialization

A vulnerability was discovered in ImageMagick where a specially created SVG file loads itself and causes a segmentation fault

CVE-2023-1289 5.5 - Medium - March 23, 2023

A vulnerability was discovered in ImageMagick where a specially created SVG file loads itself and causes a segmentation fault. This flaw allows a remote attacker to pass a specially crafted SVG file that leads to a segmentation fault, generating many trash files in "/tmp," resulting in a denial of service. When ImageMagick crashes, it generates a lot of trash files. These trash files can be large if the SVG file contains many render actions. In a denial of service attack, if a remote attacker uploads an SVG file of size t, ImageMagick generates files of size 103*t. If an attacker uploads a 100M SVG, the server will generate about 10G.

NULL Pointer Dereference

There is a flaw in convert2rhel

CVE-2022-0851 5.5 - Medium - August 29, 2022

There is a flaw in convert2rhel. When the --activationkey option is used with convert2rhel, the activation key is subsequently passed to subscription-manager via the command line, which could allow unauthorized users locally on the machine to view the activation key via the process command line via e.g. htop or ps. The specific impact varies upon the subscription, but generally this would allow an attacker to register systems purchased by the victim until discovered; a form of fraud. This could occur regardless of how the activation key is supplied to convert2rhel because it involves how convert2rhel provides it to subscription-manager.

Information Disclosure

There is a flaw in convert2rhel

CVE-2022-0852 5.5 - Medium - August 29, 2022

There is a flaw in convert2rhel. convert2rhel passes the Red Hat account password to subscription-manager via the command line, which could allow unauthorized users locally on the machine to view the password via the process command line via e.g. htop or ps. The specific impact varies upon the privileges of the Red Hat account in question, but it could affect the integrity, availability, and/or data confidentiality of other systems that are administered by that account. This occurs regardless of how the password is supplied to convert2rhel.

Privacy violation

Dangling pointer

A flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation

CVE-2022-0358 7.8 - High - August 29, 2022

A flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation. This flaw is strictly related to CVE-2018-13405. A local guest user can create files in the directories shared by virtio-fs with unintended group ownership in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of the group. This could allow a malicious unprivileged user inside the guest to gain access to resources accessible to the root group, potentially escalating their privileges within the guest. A malicious local user in the host might also leverage this unexpected executable file created by the guest to escalate their privileges on the host system.

Improper Check for Dropped Privileges

Resource Exhaustion

A flaw was found in the way the dumpable flag setting was handled when certain SUID binaries executed its descendants

CVE-2021-3864 7 - High - August 26, 2022

A flaw was found in the way the dumpable flag setting was handled when certain SUID binaries executed its descendants. The prerequisite is a SUID binary that sets real UID equal to effective UID, and real GID equal to effective GID. The descendant will then have a dumpable value set to 1. As a result, if the descendant process crashes and core_pattern is set to a relative value, its core dump is stored in the current directory with uid:gid permissions. An unprivileged local user with eligible root SUID binary could use this flaw to place core dumps into root-owned directories, potentially resulting in escalation of privileges.

Authorization

Improper Input Validation

A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode

CVE-2021-4189 5.3 - Medium - August 24, 2022

A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default.
