CVE-2026-115504CFITSIO through 4.7.0 contains an out-of-bounds write vulnerability in ffgcls2() in getcols.c that trusts attacker-controlled heap descriptor lengths for variable-length string... Executive summary A memory corruption flaw in CFITSIO, a widely used library for reading astronomy FITS files, can be triggered by opening a malformed file, which may let an attacker corrupt memory in any application that uses it. The advisory rates it HIGH with a CVSS 4.0 score of 7.1, and the fix is in the develop branch, with no tagged release containing it yet, so users should build from develop at or after commit de7da7908bca0b9ed70d219a35e8627667ced779. Technical summary This is an out-of-bounds write (CWE-787) in ffgcls2() in getcols.c, where a column width taken from attacker-controlled FITS header values is written into a fixed-size heap buffer without a bounds check. The attack vector is network with no privileges, but user interaction is required (CVSS 4.0 AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H), so a victim must process a crafted FITS file with fitsverify or a CFITSIO-linked application. Affected versions: CFITSIO 4.6.4 is confirmed, and the develop branch prior to the fix is confirmed; the CVE record covers CFITSIO through 4.7.0. The fix adds a bounds check in ffgcls2() and touches utilities/fvrf_data.c, merged as PR #184 on 2026-09-14. No workaround is stated, and no detection guidance is stated. Exploitation in the wild is not stated. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
