Name of the Vulnerable Software and Affected Versions: Tencent WeChat version 2.9.5 Description: This issue allows remote attackers to disclose sensitive information on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the WXAM decoder due to the lack of proper validation of user-supplied data, resulting in a read past the end of an allocated buffer. An attacker can leverage this, in conjunction with other issues, to execute arbitrary code in the context of the current process. Recommendations: For version 2.9.5, as a temporary workaround, consider disabling the WXAM decoder function until a patch is available. Restrict access to potentially malicious pages or files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.

Name of the Vulnerable Software and Affected Versions: Tencent WeChat version 7.0.18 Description: This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the WXAM Decoder due to the lack of proper validation of user-supplied data, resulting in a memory access past the end of an allocated object. An attacker can leverage this to execute code in the context of the current process. Recommendations: For Tencent WeChat version 7.0.18, as a temporary workaround, consider disabling the WXAM Decoder until a patch is available. Restrict access to potentially malicious pages or files to minimize the risk of exploitation. 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** Foxit Studio Photo version 3.6.6.922 **Description** This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the parsing of EZI files due to the lack of proper validation of user-supplied data, resulting in a write past the end of an allocated structure. An attacker can leverage this to execute code in the context of the current process. **Recommendations** For Foxit Studio Photo version 3.6.6.922, consider disabling the parsing of EZI files as a temporary workaround until a patch is available. Restrict access to potentially malicious pages or files to minimize the risk of exploitation. 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: Microsoft Visual Studio (affected versions not specified) Description: A remote code execution issue exists in Microsoft Visual Studio due to improper handling of objects in memory. This could allow an attacker to run arbitrary code in the context of the current user. If the user has administrative rights, the attacker could take control of the system, install programs, view, change, or delete data, or create new accounts with full user rights. The vulnerability can be exploited by convincing a user to open a specially crafted file with an affected version of Visual Studio. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
