CVE-2015-6581

Status: ModifiedHigh (7.5)—

Double free vulnerability in the opj_j2k_copy_default_tcp_and_create_tcd function in j2k.c in OpenJPEG before r3002, as used in PDFium in Google Chrome before 45.0.2454.85, allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) by triggering a memory-allocation failure.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
