SCA: security update for resdata (GHSA-pr85-w493-9w3x)
critical Tenable Self-Hosted Container Security Plugin ID 446103
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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. (CVE-2026-55209)
Solution
Update the resdata library and its related packages to version 6.2.9 or later.See Also
