Lifecycle Timeline
1DescriptionNVD
An issue was discovered in gravity through 0.8.1. A heap-buffer-overflow exists in the function gnode_function_add_upvalue located in gravity_ast.c. It allows an attacker to cause code Execution.
AnalysisAI
An issue was discovered in gravity through 0.8.1. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available and 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. An issue was discovered in gravity through 0.8.1. A heap-buffer-overflow exists in the function gnode_function_add_upvalue located in gravity_ast.c. It allows an attacker to cause code Execution. Affected products include: Creolabs Gravity. Version information: through 0.8.1..
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).
