A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. This flaw allows a malicious privileged user within the guest to crash the QEMU process on the host, resulting in a denial of service.Show less

A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.Show less

A DMA reentrancy issue was found in the NVM Express Controller (NVME) emulation in QEMU. This CVE is similar to CVE-2021-3750 and, just like it, when the reentrancy write triggers the reset function nvme_ctrl_reset(), data structs will be freed leading to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition or, potentially, executing arbitrary code within the context of the QEMU process on the host.Show less

A symbolic link issue was found in rpm. It occurs when rpm sets the desired permissions and credentials after installing a file. A local unprivileged user could use this flaw to exchange the original file with a symbolic link to a security-critical file and escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.Show less

A race condition vulnerability was found in rpm. A local unprivileged user could use this flaw to bypass the checks that were introduced in response to CVE-2017-7500 and CVE-2017-7501, potentially gaining root privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.Show less

A flaw in Apache libapreq2 versions 2.16 and earlier could cause a buffer overflow while processing multipart form uploads. A remote attacker could send a request causing a process crash which could lead to a denial of service attack.Show less

An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS 15.6.1 and iPadOS 15.6.1, macOS Monterey 12.5.1, Safari 15.6.1. Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited.Show less

Multiple out-of-bounds write issues were addressed with improved bounds checking. This issue is fixed in macOS Monterey 12.5, watchOS 8.7, tvOS 15.6, iOS 15.6 and iPadOS 15.6. An app may be able to disclose kernel memory.Show less

A flaw was found in unzip. The vulnerability occurs due to improper handling of Unicode strings, which can lead to a null pointer dereference. This flaw allows an attacker to input a specially crafted zip file, leading to a crash or code execution.Show less

VMware Tools (12.0.0, 11.x.y and 10.x.y) contains a local privilege escalation vulnerability. A malicious actor with local non-administrative access to the Guest OS can escalate privileges as a root user in the virtual machine.Show less

A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows a local user on a vulnerable system to unmount other users' filesystems that are either world-writable themselves (like /tmp) or mounted in a world-writable directory. An attacker may use this flaw to cause a denial of service to applications that use the affected filesystems.Show less

A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows an unprivileged local attacker to unmount FUSE filesystems that belong to certain other users who have a UID that is a prefix of the UID of the attacker in its string form. An attacker may use this flaw to cause a denial of service to applications that use the affected filesystems.Show less
