| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
OpenJPEG versions 2.3.1 through 2020-01-28
Description
The issue is related to a heap-based buffer overflow in the
opj t1 clbl decode processor function of the OpenJPEG library, specifically in the openjp2/t1.c file when qmfbid==1. This can be exploited by a remote attacker to cause a denial of service or impact the confidentiality, integrity, and availability of protected information.Recommendations
For OpenJPEG versions 2.3.1 through 2020-01-28, consider disabling the
opj t1 clbl decode processor function as a temporary workaround until a patch is available. Restrict access to the openjp2/t1.c module to minimize the risk of exploitation. Avoid using the qmfbid variable in the affected function until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
