An issue was discovered in OpenJPEG 2.3.0. It allows remote attackers to cause a
denial of service (attempted excessive memory allocation) in opj_calloc in
openjp2/opj_malloc.c, when called from opj_tcd_init_tile in openjp2/tcd.c, as
demonstrated by the 64-bit opj_decompress.
Created openjpeg tracking bugs for this issue:
Affects: fedora-all [bug 1670983]
This is essentially a memory exhaustion flaw in the way, the decompressor allocates memory, caused by specially-crafted JPEG2000 file headers. The only impact of this flaw is machine hang, depending on the amount of memory available on the system.
