Comment 2 Tomas Hoger 2017-12-05 21:21:08 UTC
This issue, along with the related CVE-2017-13750 (bug 1488963) was now reported upstream via:


Note that the two assertions triggered in the jpc_dec_process_siz() function were only introduced in Jasper version 2.0.12 and hence these CVEs are not applicable to older versions.
