Severity: Normal Title: blktrace: Buffer overflow Date: July 08, 2021 Bugs: #655146 ID: 202107-15

Synopsis ========
A buffer overflow in blktrace might allow arbitrary code execution.
Background ==========
blktrace shows detailed information about what is happening on a block device IO queue.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-block/blktrace < 1.2.0_p20210419122502>= 1.2.0_p20210419122502
Description ===========
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 ==========
There is no known workaround at this time.
Resolution ==========
All blktrace users should upgrade to the latest version:
# emerge --sync # emerge -a --oneshot -v ">=sys-block/blktrace-1.2.0_p20210419122502"
