A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2SESSIONSETUP and SMB2LOGOFF commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel.
An unspecified vulnerability in Java SE related to the VM component could allow an unauthenticated attacker to cause no confidentiality impact, high integrity impact, and no availability impact.
A malicious server can serve excessive amounts of Set-Cookie: headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on foo.example.com can set cookies that also would match for bar.example.com, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method.
An issue was discovered in the Linux Kernel from 4.18 to 4.19, an improper update of sock reference in TCP pacing can lead to memory/netns leak, which can be used by remote clients.
Accelerate Framework. A memory consumption issue was addressed with improved memory handling.
A insufficiently protected credentials vulnerability in fixed in curl 7.83.0 might leak authentication or cookie header data on HTTP redirects to the same host but another port number.
An out-of-bounds read vulnerability was discovered in the PCRE2 library in the getrecursedatalength() function of the pcre2jitcompile.c file. This issue affects recursions in JIT-compiled regular expressions caused by duplicate data transfers.
An out-of-bounds read vulnerability was discovered in the PCRE2 library in the compilexclassmatchingpath() function of the pcre2jitcompile.c file. This involves a unicode property matching issue in JIT-compiled regular expressions. The issue occurs because the character was not fully read in case-less matching within JIT.
An unspecified vulnerability in Java SE related to the 2D component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 7u321, 8u311, 11.0.13; Oracle GraalVM Enterprise Edition: 20.3.4 and 21.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM Enterprise Edition. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.1 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
An integer overflow flaw was found in the fix applied to the BMPImageReader class implementation in the ImageIO component of OpenJDK to address the CVE-2021-35586 (bug 2015308) issue. This issue could allow a specially-crafted BMP image to bypass previously applied protection and cause a Java application to allocate an excessive amount of memory when opened.
An unspecified vulnerability in Java SE related to the Serialization component could allow an unauthenticated attacker to cause no confidentiality impact, low integrity impact, and no availability impact.
An out-of-bounds heap read in Busybox's unlzma applet leads to information leak and denial of service when crafted LZMA-compressed input is decompressed. This can be triggered by any applet/format that
A NULL pointer dereference in Busybox's hush applet leads to denial of service when processing a crafted shell command, due to missing validation after a \x03 delimiter character. This may be used for DoS under very rare conditions of filtered command input.
An attacker-controlled pointer free in Busybox's hush applet leads to denial of service and possible code execution when processing a crafted shell command, due to the shell mishandling the &&& string. This may be used for remote code execution under rare conditions of filtered command input.
A NULL pointer dereference in Busybox's man applet leads to denial of service when a section name is supplied but no page argument is given
An incorrect handling of a special element in Busybox's ash applet leads to denial of service when processing a crafted shell command, due to the shell mistaking specific characters for reserved characters. This may be used for DoS under rare conditions of filtered command input.
A flaw was found in curl in the way curl handles credentials when downloading content using the Metalink feature. This flaw allows malicious actors controlling a hosting server to gain access to credentials provided while downloading content without the user's knowledge. The highest threat from this vulnerability is to confidentiality.
A flaw was found in systemd. Attacker controlled alloca() in function unitnamepathescape() leads to a crash in systemd and ultimately a kernel panic. Systemd parses the content of /proc/self/mountinfo and each mountpoint is passed to mountsetupunit(), which calls unitnamepathescape() underneath to duplicate the string through alloca(). A local attacker who is able to mount a filesystem on a very long path can crash systemd and the whole system.

An unspecified vulnerability in Java SE related to the Libraries component could allow an unauthenticated attacker to cause no confidentiality impact, high integrity impact, and no availability impact.
A flaw was found in the way libcurl handled TLS 1.3 session tickets. A malicious HTTPS proxy could possibly use this flaw to make libcurl resume a TLS session it previously had with the proxy while intending to resume a TLS session with a target server, making it possible for the proxy to perform a man-in-the-middle attack.
curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request.
ssh-agent in OpenSSH before 8.5 has a double free that may be relevant in a few less-common scenarios, such as unconstrained agent-socket access on a legacy operating system, or the forwarding of an agent to an attacker-controlled host.
selinuxeditcopytfiles in sudoedit in Sudo before 1.9.5 allows a local unprivileged user to gain file ownership and escalate privileges by replacing a temporary file with a symlink to an arbitrary file target. This affects SELinux RBAC support in permissive mode. Machines without SELinux are not vulnerable.
The sudoedit personality of Sudo before 1.9.5 may allow a local unprivileged user to perform arbitrary directory-existence tests by winning a sudoedit.c race condition in replacing a user-controlled directory by a symlink to an arbitrary path.
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.
An issue was discovered in the Linux kernel through 5.10.1, as used with Xen through 4.14.x. The Linux kernel PV block backend expects the kernel thread handler to reset ring->xenblkd to NULL when stopped. However, the handler may not have time to run if the frontend quickly toggles between the states connect and disconnect. As a consequence, the block backend may re-use a pointer after it was freed. A misbehaving guest can trigger a dom0 crash by continuously connecting / disconnecting a block frontend. Privilege escalation and information leaks cannot be ruled out. This only affects systems with a Linux blkback.
A Null Pointer Dereference vulnerability exists in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.34, in bfdelfgetsymbolversionstring, as demonstrated in nm-new, that can cause a denial of service via a crafted file.
