SEH Buffer Overflows in AIDA64 Enable Local Arbitrary Code Execution
Two high-severity vulnerabilities, CVE-2019-25629 and CVE-2019-25631, affect AIDA64 5.99.4900 products and can lead to local arbitrary code execution through structured exception handler (SEH) buffer overflows. The flaws were reported for AIDA64 Extreme and AIDA64 Business, respectively, and both are classified as CWE-787 with a CVSS v3.1 score vector of AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating high impact across confidentiality, integrity, and availability.
In CVE-2019-25629, an attacker can abuse the Hardware Monitoring logging feature in AIDA64 Extreme by supplying a malicious CSV log file path, triggering shellcode execution when the application processes that path. In CVE-2019-25631, AIDA64 Business is vulnerable through the SMTP display name field in preferences or the report wizard, where an attacker can overwrite SEH pointers and use egg hunter shellcode to gain code execution. Public references for both issues include vendor pages, Exploit-DB listings, and VulnCheck advisories.

LanSpy 2.0.1.159 Local Buffer Overflow Flaws Enable Potential Code Execution
Two high-severity vulnerabilities, `CVE-2018-25265` and `CVE-2018-25268`, were documented for **LanSpy 2.0.1.159**, affecting the application's scan functionality and exposing users to local buffer overflow attacks. The flaws were classified as `CWE-787` and can let an attacker trigger memory corruption by supplying oversized input in the scan section or scan field, causing application crashes and creating a path to arbitrary code execution. The published details indicate that `CVE-2018-25265` can be exploited through structured exception handling (SEH), including egghunter-based shellcode discovery and controlled jumps, while `CVE-2018-25268` allows instruction pointer overwrite with a payload consisting of 688 bytes of padding followed by 4 bytes of attacker-controlled data. Both entries were assigned high-impact CVSS v3.1 and CVSS v4.0 severity metrics, and the records reference material from **LizardSystems**, **Exploit-DB**, and **VulnCheck**.

SEH Buffer Overflows in Allok Media Converters Enable Local Code Execution
Three AllokSoft multimedia applications were assigned CVEs for **buffer overflow flaws** in their `License Name` registration field that can lead to **arbitrary code execution**. The affected products are **Allok soft WMV to AVI MPEG DVD WMV Converter 4.6.1217** (`CVE-2018-25314`), **Allok AVI to DVD SVCD VCD Converter 4.0.1217** (`CVE-2018-25302`), and **Allok Video to DVD Burner 2.6.1217** (`CVE-2018-25303`). The vulnerabilities were classified under **CWE-120** and **CWE-121**, with CVSS v3.1 and v4.0 vectors added to the records. The published descriptions say a local attacker can trigger the flaws by supplying an oversized string in the registration dialog, causing a **structured exception handler (SEH) overwrite** and execution of embedded shellcode with the application's privileges. One advisory describes exploitation after clicking the Register button, while another notes a payload with junk data, SEH chain pointers, and shellcode pasted into the field. References attached to the CVE records include **Exploit-DB**, **AllokSoft**, and **VulnCheck** advisories, indicating publicly documented exploit details for the affected legacy software.

New CVEs Detail Stack Buffer Overflows in Flat Assembler and SC
Two newly recorded CVEs describe **stack-based buffer overflow** flaws that can lead to arbitrary code execution in legacy software components. **CVE-2017-20228** affects **Flat Assembler 1.71.21**, where oversized assembly input exceeding **5895 bytes** can overwrite the instruction pointer and enable **return-oriented programming (ROP)** for shell command execution. The issue is classified as **`CWE-787`** and carries high impact to confidentiality, integrity, and availability. A second entry, **CVE-2018-25222**, affects **SC v7.16** and similarly allows code execution through oversized input, in this case beyond **1052 bytes**, resulting in instruction pointer overwrite and shellcode execution in the application context. The vulnerability is also classified as **`CWE-787`**, with CVSS scoring indicating low attack complexity and severe impact, and both CVEs include references to **Exploit-DB** and **VulnCheck advisories**, signaling the availability of public technical details for defenders to review.
