Summary
CFITSIO, a widely used C library for reading and writing FITS astronomical data files, is affected by this flaw. A specially crafted FITS file can trigger a memory overflow that may allow an attacker to run arbitrary code on the affected system.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
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.
