Comment 2 Tomas Hoger 2017-12-05 16:21:11 EST

This issue, along with the related CVE-2017-13746 (bug 1488959) was now reported upstream via:

https://github.com/mdadams/jasper/issues/165

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.
