Synopsis

Description

The remote host is affected by the vulnerability described in GLSA-202107-15 (blktrace: Buffer overflow)

A crafted file could cause a buffer overflow in the ‘dev_map_read’
function because the device and devno arrays are too small.
Impact :

A remote attacker could entice a user to open a specially crafted file using blktrace, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
Workaround :
