Security Vulnerabilities - CVEs Published In April 2026
Iperius Backup 5.8.1 contains a local buffer overflow vulnerability in the structured exception handling (SEH) mechanism that allows local attackers to execute arbitrary code by supplying a malicious file path. Attackers can create a backup job with a crafted payload in the external file location field that triggers a buffer overflow when the backup job executes, enabling code execution with application privileges.

Angry IP Scanner for Linux 3.5.3 contains a denial of service vulnerability that allows local attackers to crash the application by supplying malformed input to the port selection field. Attackers can craft a malicious string containing buffer overflow patterns and paste it into the Preferences Ports tab to trigger an application crash.

LanSpy 2.0.1.159 contains a local buffer overflow vulnerability in the scan section that allows local attackers to execute arbitrary code by exploiting structured exception handling mechanisms. Attackers can craft malicious payloads using egghunter techniques to locate and execute shellcode, triggering code execution through SEH chain manipulation and controlled jumps.

Terminal Services Manager 3.1 contains a stack-based buffer overflow vulnerability in the computer names field that allows local attackers to execute arbitrary code by triggering structured exception handling. Attackers can craft a malicious input file with shellcode and jump instructions that overwrite the SEH handler pointer to execute calc.exe or other payloads when imported through the add computers wizard.

An issue was discovered in guardsix (formerly Logpoint) ODBC Enrichment Plugins before 5.2.1 (5.2.1 is used in guardsix 7.9.0.0). A logic flaw allowed stored database credentials to be reused after modification of the target Host, IP address, or Port. When editing an existing Enrichment Source, previously stored credentials were retained even if the connection endpoint was changed. An authenticated Operator user could redirect the database connection to unintended internal systems, resulting in SSRF and potential misuse of valid stored credentials.

A flaw was found in libefiboot, a component of efivar. The device path node parser in libefiboot fails to validate that each node's Length field is at least 4 bytes, which is the minimum size for an EFI (Extensible Firmware Interface) device path node header. A local user could exploit this vulnerability by providing a specially crafted device path node. This can lead to infinite recursion, causing stack exhaustion and a process crash, resulting in a denial of service (DoS).

A flaw was found in InstructLab. The `linux_train.py` script hardcodes `trust_remote_code=True` when loading models from HuggingFace. This allows a remote attacker to achieve arbitrary Python code execution by convincing a user to run `ilab train/download/generate` with a specially crafted malicious model from the HuggingFace Hub. This vulnerability can lead to complete system compromise.

A flaw was found in GNU Emacs. This vulnerability, a memory corruption issue, occurs when Emacs processes specially crafted SVG (Scalable Vector Graphics) CSS (Cascading Style Sheets) data. A local user could exploit this by convincing a victim to open a malicious SVG file, which may lead to a denial of service (DoS) or potentially information disclosure.
