Comment 2 Tomas Hoger 2017-12-05 21:21:11 UTC
This issue, along with the related CVE-2017-13746 (bug 1488959) 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.

Comment 4 Tomas Hoger 2020-12-11 14:21:34 UTC
Upstream commit:


Fixed upstream in jasper 2.0.17.
