An out-of-bounds write caused by numeric truncation Samsung Open Source Escargot on Linux x86-64 allows an attacker who can supply JavaScript for execution to corrupt native memory and crash the host process via a crafted class definition whose instance initialization entry count exceeds UINT16_MAX.
This issue affects Escargot: 5dc93606abd42b859045add05d704a038e197359.
AnalysisAI
Out-of-bounds write in Samsung's Escargot JavaScript engine on Linux x86-64 allows process crash when a crafted class definition is supplied for execution. Numeric truncation (CWE-197) occurs when an instance initialization entry count exceeding UINT16_MAX is stored in a uint16_t field, producing a corrupted count that drives subsequent out-of-bounds memory writes and host process termination. …

Vulnerability AssessmentAI
| Exploitation | The attacker must be able to supply arbitrary JavaScript for execution by a process embedding Escargot on Linux x86-64. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 6.2 with vector AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H characterizes this as a local, no-auth denial-of-service with no confidentiality or integrity impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update Escargot to a commit that incorporates the memory-safety fix from PR #1660 (https://github.com/Samsung/escargot/pull/1660); note that the available PR diff shows only CI/workflow changes, so verify independently that the upstream C++ fix for numeric truncation in class instance initialization is included before deploying. … Detailed patch versions, workarounds, and compensating controls in full report. |
