Description OSIDB Bzimport 2026-07-01 20:22:45 UTC 
A double-free vulnerability exists in GIMP's Paint Shop Pro (PSP) file format parser. In read_layer_block() in file-psp.c, the variable name is allocated, used, and freed each loop iteration. On the error path in the 2nd iteration, fread fails before g_malloc for name, so the stale pointer from iteration 1 is freed again via g_free(name).
