A heap-based buffer overflow exists in XML Decompression DecodeTreeBlock in AT&T Labs Xmill 0.7. A crafted input file can lead to remote code execution. This is not the same as any of: CVE-2021-21810, CVE-2021-21811, CVE-2021-21812, CVE-2021-21815, CVE-2021-21825, CVE-2021-21826, CVE-2021-21828, CVE-2021-21829, or CVE-2021-21830. NOTE: This vulnerability only affects products that are no longer supported by the maintainer
AnalysisAI
A heap-based buffer overflow exists in XML Decompression DecodeTreeBlock in AT&T Labs Xmill 0.7. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. A heap-based buffer overflow exists in XML Decompression DecodeTreeBlock in AT&T Labs Xmill 0.7. A crafted input file can lead to remote code execution. This is not the same as any of: CVE-2021-21810, CVE-2021-21811, CVE-2021-21812, CVE-2021-21815, CVE-2021-21825, CVE-2021-21826, CVE-2021-21828, CVE-2021-21829, or CVE-2021-21830. NOTE: This vulnerability only affects products that are no longer supported by the maintainer Affected products include: Att Xmill, Schneider-Electric Ecostruxure Control Expert, Schneider-Electric Ecostruxure Process Expert, Schneider-Electric Remoteconnect.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
