Published: 26 June 2019

Out-of-bounds accesses in the functions pi_next_lrcp, pi_next_rlcp, pi_next_rpcl, pi_next_pcrl, pi_next_rpcl, and pi_next_cprl in openmj2/pi.c in OpenJPEG through 2.3.0 allow remote attackers to cause a denial of service (application crash).

Debian binary packages built with BUILD_MJ2:BOOL=OFF
According to https://github.com/uclouvain/openjpeg/pull/1168#commitcomment-32961642 the patch https://github.com/uclouvain/openjpeg/commit/e1740e7ce79d0a1676db4da0f4189b64e85f52cb was reverted because it did not compile. Code is not present in upstream master anymore

according to the comments available in issue 1328 of openjpeg
(https://github.com/uclouvain/openjpeg/issues/1328), this issue
will not be fixed by upstream, as the vulnerable components
were simply removed from the code in pull request #1350. For
this reason, xenial and trusty cannot be patched for this issue
in package openjpeg. There was a patch available, which was commit
c277159986c, however, it did not compile, and therefore was
reverted by upstream. No new fixes for this issue were made
available, the solution apparently being the removal of the code
that contains the vulnerability.
