Division-by-zero vulnerabilities in the functions pi_next_pcrl,
pi_next_cprl, and pi_next_rpcl in openmj2/pi.c in OpenJPEG through 2.3.0
allow remote attackers to cause a denial of service (application crash).
Author | Note |
---|---|
ebarretto | Marking emscripten ignored as openjpeg2 code is only for test/example. |
mdeslaur | Ubuntu openjpeg2 packages are built with BUILD_MJ2:BOOL=OFF, so the vulnerable code is not compiled |
ccdm94 | the openjpeg package does not include the file patched by commit c5bd64ea146. Before the refactoring, there was a single pi.c file, which according to the code itself, seems to be affected by this vulnerability, however, it looks like the vulnerability in this case is related to CVE-2018-14423 instead, which has a very similar patch (bd88611ed9a). |
