Vulnerabilities

The fetch(3) library uses environment variables for passing certain information, including the revocation file pathname. The environment variable name used by fetch(1) to pass the filename to the library was incorrect, in effect ignoring the option.<br /> <br /> Fetch would still connect to a host presenting a certificate included in the revocation file passed to the --crl option.

Account users in Apache CloudStack by default are allowed to register templates to be downloaded directly to the primary storage for deploying instances. Due to missing validation checks for KVM-compatible templates in CloudStack 4.0.0 through 4.18.2.4 and 4.19.0.0 through 4.19.1.2, an attacker that can register templates, can use them to deploy malicious instances on KVM-based environments and exploit this to gain access to the host filesystems that could result in the compromise of resource integrity and confidentiality, data loss, denial of service, and availability of KVM-based infrastructure managed by CloudStack.<br /> <br /> <br /> Users are recommended to upgrade to Apache CloudStack 4.18.2.5 or 4.19.1.3, or later, which addresses this issue. <br /> <br /> Additionally, all user-registered KVM-compatible templates can be scanned and checked that they are flat files that should not be using any additional or unnecessary features. For example, operators can run the following command on their file-based primary storage(s) and inspect the output. An empty output for the disk being validated means it has no references to the host filesystems; on the other hand, if the output for the disk being validated is not empty, it might indicate a compromised disk. However, bear in mind that (i) volumes created from templates will have references for the templates at first and (ii) volumes can be consolidated while migrating, losing their references to the templates. Therefore, the command execution for the primary storages can show both false positives and false negatives.<br /> <br /> <br /> for file in $(find /path/to/storage/ -type f -regex [a-f0-9\-]*.*); do echo "Retrieving file [$file] info. If the output is not empty, that might indicate a compromised disk; check it carefully."; qemu-img info -U $file | grep file: ; printf "\n\n"; done<br /> For checking the whole template/volume features of each disk, operators can run the following command:<br /> <br /> <br /> for file in $(find /path/to/storage/ -type f -regex [a-f0-9\-]*.*); do echo "Retrieving file [$file] info."; qemu-img info -U $file; printf "\n\n"; done

The NVMe driver function nvme_opc_get_log_page is vulnerable to a buffer over-read from a guest-controlled value.

The virtio_vq_recordon function is subject to a time-of-check to time-of-use (TOCTOU) race condition.

A guest can trigger an infinite loop in the hda audio driver.

The command ctl_persistent_reserve_out allows the caller to specify an arbitrary size which will be passed to the kernel&amp;#39;s memory allocator.

APTIOV contains a vulnerability in the BIOS where a user or attacker may cause an improper restriction of operations within the bounds of a memory buffer over the network. A successful exploitation of this vulnerability may lead to code execution outside of the intended System Management Mode.

A remote code execution vulnerability exists in the affected<br /> product. The vulnerability allows users to save projects within the public<br /> directory allowing anyone with local access to modify and/or delete files. Additionally,<br /> a malicious user could potentially leverage this vulnerability to escalate<br /> their privileges by changing the macro to execute arbitrary code.

APTIOV contains a vulnerability in BIOS where an attacker may cause an Improper Restriction of Operations within the Bounds of a Memory Buffer by local. Successful exploitation of this vulnerability may lead to privilege escalation and potentially arbitrary code execution, and impact Integrity.

An exploit is possible where an actor with physical access can manipulate SPI flash without being detected.

A vulnerability was found in ZZCMS up to 2023. It has been rated as problematic. Affected by this issue is some unknown functionality of the file /admin/msg.php. The manipulation of the argument keyword leads to cross site scripting. The attack may be launched remotely. The exploit has been disclosed to the public and may be used.

APTIOV contains a vulnerability in BIOS where may cause Improper Access Control by a local attacker. Successful exploitation of this vulnerability may lead to unexpected SPI flash modifications and BIOS boot kit launches, also impacting the availability.
