تتعلق المشكلة ببروتوكول بيانات اعتماد Git، وهو بروتوكول نصي يتكون من أزواج من المفاتيح والقيم. يؤدي عدم التوافق في معالجة فواصل الأسطر بين Git و Git Credential Manager (GCM) إلى تمكين المهاجم من إنشاء عنوان URL بعيد ضار. وقد يؤدي ذلك إلى الاستيلاء على بيانات اعتماد مستودع Git بعيد آخر. وتزداد خطورة الهجوم عند استنساخ مستودعات تحتوي على وحدات فرعية باستخدام خيار الاستنساخ --recursive.

The issue concerns incorrect default permissions in some memory controller configurations for Intel(R) Xeon(R) Processors when using Intel(R) Software Guard Extensions. This may allow a privileged user to potentially enable escalation of privilege via local access. The vulnerability is related to Intel Microcode and is associated with default permission settings. Exploitation of the vulnerability could allow an attacker to access confidential data, compromise data integrity, and cause a denial of service.

The issue concerns an authentication bypass when processing SAML responses containing multiple Assertion elements. This has been corrected in version 0.4.9. There are no workarounds other than upgrading to a fixed version.

The issue is related to an out-of-bounds writing problem in Apache Commons BCEL, which can be exploited to produce arbitrary bytecode. This could be abused in applications that pass attacker-controllable data to the affected APIs, giving the attacker more control over the resulting bytecode than otherwise expected.

A remote attacker may be able to bypass SAML authentication on a website using passport-saml. A successful attack requires that the attacker is in possession of an arbitrary IDP signed XML element. Depending on the IDP used, fully unauthenticated attacks might also be feasible if generation of a signed message can be triggered.

Depending on the IDP used, fully unauthenticated attacks might also be feasible if generation of a signed message can be triggered.

An information disclosure issue exists due to incorrect restriction of XML external entity references, potentially allowing a remote attacker to access confidential information. This issue affects .NET Core 3.1 and .NET 6.0 applications.

The issue is related to improper input validation, which can allow a remote attacker to execute arbitrary code in the context of the current user. This is due to incorrect verification of cryptographic signatures.

The Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious XSLT stylesheets. This can be used to corrupt Java class files generated by the internal XSLTC compiler and execute arbitrary Java bytecode. Note that Java runtimes, such as OpenJDK, include repackaged copies of Xalan.

The issue concerns the BPG parser in Apache Tika, which may allocate an excessive amount of memory when processing carefully crafted files.

The issue is related to an integer overflow in cmark-gfm's table row parsing, which may lead to heap memory corruption when parsing tables with more than UINT16 MAX columns. This can result in Information Leak or Arbitrary Code Execution, depending on how and where cmark-gfm is used. If cmark-gfm is used for rendering remote user-controlled markdown, this may lead to Remote Code Execution (RCE) in applications employing affected versions of the cmark-gfm library.

The issue is related to an integer overflow vulnerability in the CommonMarker library. This vulnerability can be exploited by remote attackers to cause heap memory corruption, potentially leading to an information leak or remote code execution. The vulnerability occurs when parsing tables with marker rows that contain more than UINT16 MAX columns.

A bug was found in containerd where containers launched through containerd’s CRI implementation with a specially-crafted image configuration could gain access to read-only copies of arbitrary files and directories on the host. This may bypass any policy-based enforcement on container setup, including a Kubernetes Pod Security Policy, and expose potentially sensitive information. Kubernetes and crictl can both be configured to use containerd’s CRI implementation.

The issue is related to an integer overflow in the 16-bit length field for the byte array attribute type in the netlink serialization system used by runc. This allows an attacker with control over the container configuration to bypass namespace restrictions by adding a malicious netlink payload. The main users impacted are those who allow untrusted images with untrusted configurations to run on their machines, such as with shared cloud infrastructure.

The issue is related to a use-after-free vulnerability in the arch/x86/kvm/svm/nested.c component of the Linux kernel, specifically affecting AMD KVM guests. This vulnerability can be exploited to bypass access control on host OS MSRs when there are nested guests, due to a TOCTOU race condition associated with a VMCB12 double fetch in nested svm vmrun. The vulnerability allows an attacker to execute code outside of the guest system, potentially leading to privilege escalation.

Name of the Vulnerable Software and Affected Versions: Google Chrome versions prior to 88.0.4324.96 Mozilla Firefox versions prior to 84.0.2 Firefox ESR versions prior to 84.0.2 Firefox for Android versions prior to 84.0.2 Description: The issue is related to a use-after-free vulnerability in the WebRTC implementation, specifically in the COOKIE-ECHO extension. This vulnerability can be exploited by a remote attacker using a crafted SCTP packet, potentially leading to heap corruption or arbitrary code execution. The vulnerability is caused by accessing memory after it has been freed in the COOKIE-ECHO handler. Recommendations: For Google Chrome versions prior to 88.0.4324.96, update to version 88.0.4324.96 or later. For Mozilla Firefox versions prior to 84.0.2, update to version 84.0.2 or later. For Firefox ESR versions prior to 84.0.2, update to version 84.0.2 or later. For Firefox for Android versions prior to 84.0.2, update to version 84.0.2 or later. As a temporary workaround, consider disabling WebRTC until a patch is available. Restrict access to the COOKIE-ECHO extension to minimize the risk of exploitation. Avoid using the `COOKIE-ECHO` handler in the affected SCTP packet until the issue is resolved.

The issue arises from insufficient input validation in Git's "credential helper" component, allowing an attacker to trick Git into sending private credentials to a host controlled by the attacker. This can be achieved by crafting a specially formatted URL containing an encoded newline, which injects unintended values into the credential helper protocol stream. As a result, the credential helper may retrieve the password for one server and send it to another server, potentially leading to unauthorized access to protected information. The vulnerability can be triggered by feeding a malicious URL to `git clone`, and the likely vector would be through systems that automatically clone URLs not visible to the user, such as Git submodules or package systems built around Git.

The issue is related to the hpack dht insert function in the HPACK decoder, which can be exploited by a remote attacker via a crafted HTTP/2 request. This could lead to writing arbitrary bytes around a certain location on the heap, possibly causing remote code execution. The vulnerability may allow an attacker to gain unauthorized access to confidential data, cause a denial of service, or impact data integrity.

The issue is related to a buffer overflow in the FreeTDS library. This can potentially allow a remote attacker to cause a denial of service or execute arbitrary code.

The issue is related to a Use-after-Free in the KVM implementation of the Linux kernel. This could potentially allow an attacker to cause a denial of service or execute arbitrary code.
