Commit message: [trunk] Correct potential double free on malloc failure in opj_j2k_copy_default_tcp_and_create_tcp (fixes issue 492)
CVE: CVE-2015-6581
CWE: NVD-CWE-Other
Vulnerability description: 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.
