Commit message: Encoder: grow again buffer size in opj_tcd_code_block_enc_allocate_data() (fixes #1283)
CVE: CVE-2020-27814
CWE: CWE-122
Vulnerability description: A heap-buffer overflow was found in the way openjpeg2 handled certain PNG format files. An attacker could use this flaw to cause an application crash or in some cases execute arbitrary code with the permission of the user running such an application.
