FreeBSD: VID-b7d56d0b-7a11-11e6-af78-589cfc0654e1 (CVE-2016-7163): openjpeg -- multiple vulnerabilities

Tencent's Xuanwu LAB reports: A Heap Buffer Overflow (Out-of-Bounds Write) issue was found in function opj_dwt_interleave_v of dwt.c. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OpenJPEG. An integer overflow issue exists in function opj_pi_create_decode of pi.c. It can lead to Out-Of-Bounds Read and Out-Of-Bounds Write in function opj_pi_next_cprl of pi.c (function opj_pi_next_lrcp, opj_pi_next_rlcp, opj_pi_next_rpcl, opj_pi_next_pcrl may also be vulnerable). This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OpenJPEG.
