net-snmp - security update
Affecting net-snmp package on Debian:8
Context / Overview
A heap corruption vulnerability was discovered in net-snmp, a suite of Simple Network Management Protocol applications, triggered when parsing the PDU prior to the authentication process. A remote, unauthenticated attacker can take advantage of this flaw to crash the snmpd process (causing a denial of service) or, potentially, execute arbitrary code with the privileges of the user running snmpd.
For the oldstable distribution (jessie), these problems have been fixed in version 5.7.2.1+dfsg-1+deb8u1.
For the stable distribution (stretch), these problems have been fixed before the initial release.
We recommend that you upgrade your net-snmp packages.

OSV-Scanner
Objective: Dependency check (SCA)
Description: OSV-Scanner provides an officially supported frontend to the OSV database that connects a project’s list of dependencies with the vulnerabilities that affect them. Since the OSV.dev database is open source and distributed, it has several benefits in comparison with closed source advisory databases and scanners:
Vulnerability Layer - SCA
SCA Dependency Check is one of the important tools used to identify vulnerabilities in open-source components used in software applications. However, it primarily focuses on identifying vulnerabilities in the dependency layer of the software application. In contrast, code vulnerability layer analysis is focused on identifying vulnerabilities in the source code of the application itself, rather than the dependencies it uses. It typically involves analyzing the source code to identify security issues such as buffer overflows, injection vulnerabilities, and authentication issues, among others. While SCA Dependency Check is an important tool in identifying vulnerabilities in open-source dependencies, it may not be sufficient to ensure the overall security of the software application. To ensure comprehensive security, it is important to also perform code vulnerability layer analysis to identify vulnerabilities in the source code of the application. Incorporating both SCA Dependency Check and code vulnerability layer analysis into the software development lifecycle can help ensure that vulnerabilities are identified and remediated at both the dependency and code layers of the application. This can help prevent security issues from being introduced into the final product and improve the overall security posture of the software application.
