**Name of the Vulnerable Software and Affected Versions** NSF Unidata NetCDF-C (affected versions not specified) **Description** A flaw exists in the parsing of time units within NSF Unidata NetCDF-C, leading to a stack-based buffer overflow. This allows a remote attacker to execute arbitrary code on affected systems. Exploitation requires user interaction, such as visiting a malicious page or opening a malicious file. The issue stems from insufficient validation of user-supplied data length before copying it into a fixed-size stack buffer. An attacker can exploit this to execute code with the privileges of the current user. **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** NSF Unidata NetCDF-C (affected versions not specified) **Description** A remote code execution issue exists in NSF Unidata NetCDF-C due to an integer overflow in the handling of NC Variables. This allows for potential code execution. **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** NSF Unidata NetCDF-C (affected versions not specified) **Description** A flaw exists in the parsing of variable names, stemming from insufficient validation of user-supplied data length before copying it into a fixed-length stack-based buffer. This can allow a remote attacker to execute arbitrary code in the context of the current user. User interaction is required, such as visiting a malicious page or opening a malicious file, to trigger the issue. **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** NSF Unidata NetCDF-C (affected versions not specified) **Description** A flaw exists in the parsing of attribute names within NSF Unidata NetCDF-C, leading to a stack-based buffer overflow. This allows remote attackers to execute arbitrary code on vulnerable systems. Exploitation requires user interaction, such as visiting a malicious page or opening a malicious file. The issue stems from insufficient validation of user-supplied data length before copying it into a fixed-size stack buffer. An attacker can potentially execute code with the privileges of the current user. **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** Lua version 5.3.5 **Description** The issue is related to a use-after-free in the `lua upvaluejoin` function in `lapi.c`, which can be exploited by an attacker to cause a crash. This can be achieved by triggering a `debug.upvaluejoin` call with specific argument relationships. The vulnerability may allow a remote attacker to cause a denial of service. **Recommendations** For Lua version 5.3.5, as a temporary workaround, consider disabling the `lua upvaluejoin` function in `lapi.c` until a patch is available. Restrict access to the `debug.upvaluejoin` call to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
