**Name of the Vulnerable Software and Affected Versions** lha (affected versions not specified) **Description** The issue is related to an integer underflow in the header.c file of lha, which can be triggered by a large header size value for the level0 or level1 header in an lha archive. This can lead to a buffer overflow, allowing remote attackers to have an unspecified impact. **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** Orchard versions 1.7.3 through 1.8.2 Orchard versions 1.9.x before 1.9.1 **Description** A cross-site scripting (XSS) issue exists in the Users module, allowing remote attackers to inject arbitrary web script or HTML via the `username` when creating a new user account. This occurs because the input is not properly handled when deleting an account. **Recommendations** For Orchard versions 1.7.3 through 1.8.2, update to version 1.8.3 or later to resolve the issue. For Orchard versions 1.9.x before 1.9.1, update to version 1.9.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the Users module to minimize the risk of exploitation.
