Subject: [oCERT-2015-001] JasPer input sanitization errors

#2015-001 JasPer input sanitization errors

Description:

The JasPer project is an open source implementation for the JPEG-2000 codec.

The library is affected by an off-by-one error in a buffer boundary check in
jpc_dec_process_sot(), leading to a heap based buffer overflow, as well as
multiple unrestricted stack memory use issues in jpc_qmfb.c, leading to stack
overflow.

A specially crafted JPEG-2000 file can be used to trigger the vulnerabilities.

Affected version:

JasPer <= 1.900.1

Fixed version:

JasPer, N/A
