An integer overflow can be triggered in SQLite’s concat_ws() function. (CVE-2025-3277)
An integer overflow vulnerability exists in SQLite's concat_ws() function, leading to a heap buffer overflow of approximately 4GB. This occurs because a truncated integer is used for buffer allocation, but the original size is used when writing data, causing memory corruption. This flaw can result in arbitrary code execution. The vulnerability affects specific versions of SQLite and Node.js packages on Red Hat Enterprise Linux 8. A security update addressing this issue is available from Red Hat.
AI Analysis
Technical Summary
CVE-2025-3277 describes an integer overflow in SQLite's concat_ws() function. The overflow causes the integer used for buffer allocation to be truncated, while the original untruncated size is used during string write operations. This mismatch triggers a large heap buffer overflow (~4GB), potentially allowing arbitrary code execution. The vulnerability affects SQLite versions >=22.0.0 and <22.15.0, and Node.js versions >=3.44.0 and <3.49.1 as packaged by Red Hat. Red Hat has issued an important security advisory (RHSA-2025:4459) providing patches for affected packages in Red Hat Enterprise Linux 8.
Potential Impact
The vulnerability can lead to a large heap buffer overflow, which may be exploited to execute arbitrary code on affected systems. This poses a significant security risk, especially in environments where SQLite or the affected Node.js modules are used. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
A security update is available from Red Hat as detailed in advisory RHSA-2025:4459. Users should apply the updated Node.js 22 module packages for Red Hat Enterprise Linux 8 to remediate this vulnerability. Refer to https://access.redhat.com/articles/11258 for update instructions. No additional mitigation steps are indicated by the vendor advisory.
