Description Laura Pardo 2018-04-20 16:56:19 EDT

A flaw was discovered in GEGL through 0.3.32. The gegl_buffer_iterate_read_simple function in buffer/gegl-buffer-access.c allows remote attackers to cause a denial of service (write access violation) or possibly have unspecified other impact via a malformed PPM file, related to improper restrictions on memory allocation in the ppm_load_read_header function in operations/external/ppm-load.c.

This is fixed in all gegl04 builds. gegl04 is a natural progression of the unstable gegl03 series.
