gentoo
July 7, 2021
A buffer overflow in blktrace might allow arbitrary code execution.
Summary
A crafted file could cause a buffer overflow in the 'dev_map_read' function because the device and devno arrays are too small.
Resolution
All blktrace users should upgrade to the latest version:
# emerge --sync
# emerge -a --oneshot -v ">=sys-block/blktrace-1.2.0_p20210419122502"
