CVE Severity
Our Official Summary
A critical vulnerability was identified in libxml2, specifically within the xmlBuildQName() function, where integer overflow in buffer size calculations can lead to a stack-based buffer overflow. When a maliciously crafted input is processed, this flaw may cause memory corruption or a denial of service (DoS).
This vulnerability affects libxml2 but poses minimal risk in SpectroCloud-managed environments, as the vulnerable component resides in a container image not exposed externally. Exploiting the flaw requires internal access and malicious XML input, which is unlikely in typical SpectroCloud workloads. Additionally, container isolation and execution restrictions significantly reduce the impact, making the overall risk low.
