blktrace (aka Block IO Tracing) is vulnerable to buffer overflow attacks. This exists in the dev_map_read function in btt/devmap.c because the device and devno arrays are too small, as demonstrated by an invalid free when using the btt program with a crafted file. This may leads to a application crash.
