CVE-2017-12982

Description

The bmp_read_info_header function in bin/jp2/convertbmp.c in OpenJPEG 2.2.0 does not reject headers with a zero biBitCount, which allows remote attackers to cause a denial of service (memory allocation failure) in the opj_image_create function in lib/openjp2/image.c, related to the opj_aligned_alloc_n function in opj_malloc.c.

Techniques & Countermeasures

• CWE-119•Improper Restriction of Operations within the Bounds of a Memory Buffer

  The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
