Technical details
A CWE-843 undefined behavior vulnerability exists in the PFM loader's mmap path (vips_foreign_load_ppm_map), which aliases the mmap'd pixel data at a non-aligned offset when the text header length is not a multiple of 4 bytes. The vips_avg_scan() function subsequently dereferences this misaligned buffer through a float pointer, causing process termination on strict-alignment architectures (ARM32/SPARC) or UBSan-instrumented builds via SIGBUS or abort. Attack vector is network/local file processing with no authentication required.
