Published: 3 September 2018
An issue was discovered in OpenJPEG 2.3.0. A heap-based buffer overflow was discovered in the function t2_encode_packet in lib/openmj2/t2.c. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service or possibly unspecified other impact.
Notes
| Author | Note |
|---|---|
| mdeslaur | Ubuntu packages are built with BUILD_MJ2:BOOL=OFF, so the affected code isn't compiled |
| ccdm94 | 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. |
