Homebrew vulnerability analysis and mitigation
Overview
CVE-2023-2597 is a buffer overflow vulnerability discovered in Eclipse OpenJ9 versions prior to 0.38.0. The vulnerability exists in the implementation of the shared cache feature, which is enabled by default in OpenJ9 builds, specifically in the getCachedUTFString() function due to improper boundary checking (ASEC).
Technical details
The vulnerability stems from improper boundary checking in the getCachedUTFString() function within Eclipse OpenJ9's shared cache implementation. The issue was addressed by adding a check for string length in the function to prevent buffer overflow conditions (GitHub PR). The vulnerability has been assigned a CVSS score of 7.0 (HIGH) with the vector AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H (NetApp Security).
Impact
When successfully exploited, this vulnerability could lead to elevation of privilege and arbitrary code execution on affected systems. The high severity rating indicates potential significant impact on the confidentiality, integrity, and availability of the system (NetApp Security).
Mitigation and workarounds
The vulnerability has been fixed in Eclipse OpenJ9 version 0.38.0. Users are advised to upgrade to this version or later to mitigate the risk. The fix involves adding proper boundary checking for string length in the getCachedUTFString() function (GitHub PR).
