CyberRota Analysis
AI-GeneratedThe resdata software, used for managing result files from the Eclipse reservoir simulator, is vulnerable due to inadequate validation of input data in GRDECL files, which can lead to buffer overflows and memory corruption. This critical vulnerability can result in service termination and potential exploitation through malformed data, making it essential for users of versions prior to 6.2.9 to prioritize immediate updates. Organizations relying on this software for reservoir simulation should address this issue urgently to mitigate risks associated with untrusted file processing.

Original NVD Description
resdata is software for reading and writing result files from the Eclipse reservoir simulator. Prior to 6.2.9, resdata insufficiently validates numeric fields, grid dimensions, keyword sizes, and array indexes while parsing untrusted GRDECL files in lib/resdata/rd_kw_grdecl.cpp and lib/resdata/rd_grid.cpp. Malformed COORD, ZCORN, CORSNUM, ACTNUM, or MAPAXES data can reach rd_grid_alloc_GRDECL_kw__ with inconsistent lengths, while unbounded floating-point conversion can exceed the intended parser buffer. In a network service that accepts untrusted GRDECL files, these conditions can cause a classic buffer overflow, out-of-bounds reads, invalid array access, NULL pointer dereference, memory corruption, or service termination. This issue is fixed in version 6.2.9.
