Element OS versions prior to 1.8P1 and 12.2 are susceptible to a vulnerability that could allow an unauthenticated remote attacker to perform arbitrary code execution.
Eclipse Jetty is vulnerable to HTTP request smuggling, caused by improper handling of Chunked Transfer-Encoding chunk size. By sending a specially-crafted request, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
A flaw was found in OpenSSL. The issue in CVE-2022-1292 did not find other places in the crehash script where it possibly passed the file names of certificates being hashed to a command executed through the shell. Some operating systems distribute this script in a manner where it is automatically executed. On these operating systems, this flaw allows an attacker to execute arbitrary commands with the privileges of the script.
A flaw was found in glibc. An integer overflow in the implementation of the posixmemalign in memalign functions in the GNU C Library (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that is too small, potentially leading to heap corruption.

A vulnerability was found in curl. This issue occurs because when curl saves cookies, alt-svc, and HSTS data to local files, it makes the operation atomic by finalizing the process with a rename from a temporary name to the final target file name. This flaw leads to unpreserved file permissions, either by mistake or by a malicious actor.
Incorrect sanitation of the 302 redirect field in HTTP transport method of apt versions 1.4.8 and earlier can lead to content injection by a MITM attacker, potentially leading to remote code execution on the target machine.
glibc is vulnerable to a denial of service, caused by a memory corruption by the Name Service Cache Daemon's (nscd) netgroup cache when the NSS callback fails to store all strings in the provided buffer. A local attacker could exploit this vulnerability to corrupt memory and cause a denial of service.
Logic bug in Intel Converged Security Management Engine 11.x may allow an attacker to execute arbitrary code via local privileged access.
DISPUTED In drivers/char/virtioconsole.c in the Linux kernel before 5.13.4, data corruption or loss can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE: the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the length validation was added solely for robustness in the face of anomalous host OS behavior.
A security flaw was discovered in the Linux kernel. The vmacacheflushall() function in mm/vmacache.c mishandles sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations.

A flaw was found in the Linux kernel that allows remote attackers to cause a denial of service (xdrsetpagebase slab-out-of-bounds access) by performing many NFS 4.2 READPLUS operations. The highest threat from this vulnerability is to system availability.
A flaw was found in Apache Santuario (XML Security for Java) in the way it processed some paths. A remote attacker could use this flaw to circumvent the "secure validation" feature and disclose potentially sensitive information in local XML files.
A vulnerability was discovered in Python. A quadratic algorithm exists when processing inputs to the IDNA (RFC 3490) decoder, such that a crafted unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor, which could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied hostname.
Element Software versions prior to 12.2 and HCI versions prior to 1.8P1 are susceptible to a vulnerability which could allow an attacker to discover sensitive information by intercepting its transmission within an https session.
Element OS prior to version 12.0 and Element HealthTools prior to version 2020.04.01.04 are susceptible to a vulnerability which when successfully exploited could lead to disclosure of sensitive information.

fs/nfsd/trace.h in the Linux kernel before 5.13.4 might allow remote attackers to cause a denial of service (out-of-bounds read in strlen) by sending NFS traffic when the trace event framework is being used for nfsd.
A new software page cache side channel attack scenario was discovered in operating systems that implement the very common 'page cache' caching mechanism. A page cache stores memory pages of running programs and/or libraries in use on a system to improve performance.
A malicious user/process could use 'in memory' page-cache knowledge to infer access timings to shared memory and gain knowledge which can be used to :
- Reduce effectiveness of cryptographic strength by monitoring algorithmic behaviour. - Infer access patterns of memory to determine code paths taken (ie, observe process execution patterns) - Exfiltrate data to a blinded attacker through page-granularity access times as a side-channel.

A flaw was found in the Linux kernel on s390 architecture. The issue occurs on multiprocessing systems when one s390 CPU is in Secondary Address Mode and another CPU does a kernel page table upgrade. An inter-processor interrupt (IPI) is then sent to each active CPU to update the control registers with new page table addresses. In Secondary Address Mode the CPU's CR1 register may hold kernel space address to fetch instructions from, but after IPI processing, the same CR1 register is set to point to a user space address. An unprivileged user or process on the system may use this flaw to crash the system or escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vividstopgeneratingvidcap(), vividstopgeneratingvidout(), sdrcapstopstreaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.
An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refreshprogressmeter() in progressmeter.c.
In OpenSSH 7.9, due to accepting and displaying arbitrary stderr output from the server, a malicious server (or Man-in-The-Middle attacker) can manipulate the client output, for example to use ANSI control codes to hide additional files being transferred.
A use-after-free read flaw was found in sockgetsockopt() in net/core/sock.c due to SOPEERCRED and SOPEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a user privilege may lead to a system crash or a leak of internal kernel information.
In this, if the creds are replaced and freed at the wrong time, a use-after-free read occurs.

A vulnerability was found in sgwrite in drivers/scsi/sg.c in SCSI generic (sg) driver subsystem. An attacker with a local access and special user privilege (or root) can cause a denial of service (DoS) if allocated list is not cleaned with invalid (Sgfd sfp) pointer at the time of failure, failing this can even cause a kernel internal information leak problem.

Element Software versions prior to 12.2 and HCI versions prior to 1.8P1 are susceptible to a vulnerability which could allow an authenticated user to view sensitive information.
named contains a feature which allows operators to issue commands to a running server by communicating with the server process over a control channel, using a utility program such as rndc. A regression introduced in a recent feature change has created a situation under which some versions of named can be caused to exit with a REQUIRE assertion failure if they are sent a null command string. Affects BIND 9.9.9->9.9.9-P7, 9.9.10b1->9.9.10rc2, 9.10.4->9.10.4-P7, 9.10.5b1->9.10.5rc2, 9.11.0->9.11.0-P4, 9.11.1b1->9.11.1rc2, 9.9.9-S1->9.9.9-S9.
