In the dynamic realm of cybersecurity, staying updated on the latest vulnerabilities is imperative.
This edition of the AppSecWorld's CVE Daily Digest provides a snapshot of the vulnerabilities published in National Vulnerability Database between February 24-25, 2024.
During this period, The National Vulnerability Database published 4, and these new Common Vulnerabilities and Exposures (CVEs) are classified as follows:
Critical: 0
High: 1
Medium: 3
Low: 0
Severity Not Assigned: 0
Identifying and understanding these vulnerabilities are pivotal steps towards enhancing security measures and creating a safer digital environment.
Now, let's delve deeper into AppSecWorld's CVE Daily Digest, spotlighting the Critical and High Severity vulnerabilities that demand immediate attention.
1. CVE-2024-21502
Base Score: 7.5
Base Severity: HIGH
Exploitability Score: 3.9
Impact Score: 3.6
Description: Versions of the package fastecdsa before 2.3.2 are vulnerable to Use of Uninitialized Variable on the stack, via the curvemath_mul function in src/curveMath.c, due to being used and interpreted as user-defined type. Depending on the variable's actual value it could be arbitrary free(), arbitrary realloc(), null pointer dereference and other. Since the stack can be controlled by the attacker, the vulnerability could be used to corrupt allocator structure, leading to possible heap exploitation. The attacker could cause denial of service by exploiting this vulnerability.
