Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A buffer overflow in blktrace might allow arbitrary code execution. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
blktrace shows detailed information about what is happening on a block |
| 24 |
device IO queue. |

================= |

|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 sys-block/blktrace < 1.2.0_p20210419122502>= 1.2.0_p20210419122502 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
A crafted file could cause a buffer overflow in the 'dev_map_read' |
| 38 |
function because the device and devno arrays are too small. |
| 39 |
|
| 40 |
Impact |
| 41 |
====== |
| 42 |
|
| 43 |
A remote attacker could entice a user to open a specially crafted file |
| 44 |
using blktrace, possibly resulting in execution of arbitrary code with |
| 45 |
the privileges of the process or a Denial of Service condition. |
| 46 |
|
| 47 |
Workaround |
| 48 |
========== |
| 49 |
|
| 50 |
There is no known workaround at this time. |
| 51 |
|
| 52 |
Resolution |
| 53 |
========== |
| 54 |
|
| 55 |
All blktrace users should upgrade to the latest version: |
| 56 |
|
| 57 |
# emerge --sync |
| 58 |
# emerge -a --oneshot -v ">=sys-block/blktrace-1.2.0_p20210419122502" |
| 59 |
|
