A vulnerability was determined in JasPer up to 4.2.5. Affected by this issue is the function jpc_floorlog2 of the file src/libjasper/jpc/jpc_enc.c of the component JPEG2000 Encoder. The manipulation leads to reachable assertion. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. The patch is identified as 79185d32d7a444abae441935b20ae4676b3513d4. It is recommended to apply a patch to fix this issue.

Weakness

The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.

Extended Description

While assertion is good for catching logic errors and reducing the chances of reaching more serious vulnerability conditions, it can still lead to a denial of service. For example, if a server handles multiple simultaneous connections, and an assert() occurs in one single connection that causes all other connections to be dropped, this is a reachable assertion that leads to a denial of service.
