**Name of the Vulnerable Software and Affected Versions** Linux Kernel versions prior to the fix **Description** The issue relates to a race condition within the `Preauh HashValue()` function of the ksmbd component in the Linux kernel. This occurs when a client sends multiple session setup requests to ksmbd. The problem stems from incorrect synchronization when a shared resource is used. The vulnerability could allow an attacker to cause a denial of service. The vulnerable function is `Preauh HashValue()`. The `sess->Preauh HashValue` variable is involved in the race condition. **Recommendations** Update the Linux Kernel to the version containing the fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified) Description: A null pointer dereference error in the `generate encryptionkey` function within the ksmbd module could occur if a client sends two session setups with Kerberos v5 authentication to ksmbd. The `Preauth HashValue` is set to NULL if the session is valid, leading to the error. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified) Description: A null pointer dereference error occurs in the Linux kernel when a client sets the `PreviousSessionId` during the Kerberos session setup stage. This happens because `sess->user` is not set yet, allowing a null value to be passed to `destroy previous session()`. The issue is resolved by moving the call to `destroy previous session()` after `ksmbd krb5 authenticate()`, where `sess->user` is set. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

The vulnerable software is 7-Zip, a widely used file compression utility. The issue arises from an integer underflow in the Zstandard decompression implementation, allowing remote attackers to execute arbitrary code on affected installations of 7-Zip by crafting specially designed archive files. To exploit this issue, interaction with the 7-Zip library is required, but attack vectors may vary depending on the implementation. The problem stems from the lack of proper validation of user-supplied data, leading to an integer underflow before writing to memory, which an attacker can leverage to execute code in the context of the current process. The vulnerable versions of 7-Zip are those prior to version 24.07. Users are advised to update to version 24.07 or later to mitigate this risk. An exploit for this issue has been reported and demonstrated, highlighting the severity of the problem. #7Zip #RemoteCodeExecution #Cybersecurity #Zstandard #IntegerUnderflow #CodeExecution #Security #UpdateNow

**Name of the Vulnerable Software and Affected Versions** Windows 10 (affected versions not specified) **Description** The issue is related to a lack of access control in the Windows Update Stack component, which can be exploited to elevate privileges. An attacker must first obtain the ability to execute low-privileged code on the target system. This can allow an attacker to impact the system. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: PaperCut NG/MF versions (affected versions not specified) Description: The issue is related to an arbitrary file deletion vulnerability in PaperCut NG/MF, specifically affecting Windows servers with Web Print enabled. This vulnerability can be exploited by an attacker who obtains local login access to the Windows Server hosting PaperCut NG/MF and can execute low-privilege code directly on the server via the web-print-hot-folder. The risk is mitigated in most installations by the default Windows Server configuration, which restricts local login access to Administrators only. However, this vulnerability could pose a risk to customers who allow non-administrative users to log into the local console of the Windows environment hosting the PaperCut NG/MF application server. Recommendations: As a temporary workaround, consider restricting access to the `web-print-hot-folder` to minimize the risk of exploitation. Restrict local login access to Administrators only on the Windows Server hosting PaperCut NG/MF. Avoid allowing non-administrative users to log into the local console of the Windows environment hosting the PaperCut NG/MF application server. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
