Summary

CFITSIO through 4.7.0 Out-of-Bounds Write via ffgcls2 in getcols.c

Details

CFITSIO 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 columns. Attackers can supply a crafted FITS file that overflows a fixed 28,800-byte stack buffer and the caller's string array, enabling arbitrary code execution.
