Description Laura Pardo 2018-04-20 20:56:19 UTC 
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.

Comment 1 Laura Pardo 2018-04-20 20:57:26 UTC 
Created gegl tracking bugs for this issue:

Affects: fedora-all [bug 1570186]
Comment 3 Doran Moppert 2018-07-27 02:53:44 UTC 
Created gegl03 tracking bugs for this issue:

Affects: fedora-all [bug 1609106]
Comment 5 Debarshi Ray 2018-08-24 16:26:17 UTC 
This is fixed in all gegl04 builds. gegl04 is a natural progression of the unstable gegl03 series.
Comment 6 Josef Ridky 2021-01-28 11:08:40 UTC 
Fixed in gegl04, gegl nor gegl03 are available in Fedora.
