Name of the Vulnerable Software and Affected Versions blktrace versions 1.2.0

Description The issue is related to a buffer overflow in the dev map read function in btt/devmap.c due to the device and devno arrays being too small. This can be demonstrated by an invalid free when using the btt program with a crafted file. The exploitation of this issue may allow a remote attacker to cause a denial of service.

Recommendations For version 1.2.0, consider disabling the dev map read function in btt/devmap.c as a temporary workaround until a patch is available. Restrict access to the btt program to minimize the risk of exploitation. Avoid using the btt program with crafted files until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
