CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
tty: abort break signalling on hangup
The break ioctls can race with hangup and end up calling into a tty
driver for a device that is already gone or powered down.
Drivers must handle this race, but TCSBRK and TCSBRKP should still be
aborted to avoid calling back into the driver after a user-controlled
timeout (possibly even after the tty has been reopened).
Note that drivers should disable any break state on shutdown so just
return on hangup (calling break_ctl() again is racy and will most likely
fail for drivers handling the race). |
| In the Linux kernel, the following vulnerability has been resolved:
tty: port: fix tty_port_tty_vhangup() race
Drivers rely on tty_port_tty_vhangup() to synchronously hang up their
ports before tearing down resources as part of deregistration (e.g. on
physical disconnect).
If tty_port_tty_vhangup() races with another hangup it may however
return before the port has been shut down. This is in turn can lead to
use-after-free and NULL-pointer dereferences in racing ioctls (including
a synchronous hangup) and in processing of racing asynchronous hangups
(carrier loss).
Add the missing serialisation to tty_port_tty_vhangup() and
tty_port_hangup() so that the former does not return until the port has
been shut down also when there is a racing hangup.
Note that serial core does not use tty_port_hangup(), but it already
holds the port mutex when clearing port->tty and shutting down the port
in uart_hangup(). |
| In the Linux kernel, the following vulnerability has been resolved:
tty: vcc: hold port lock when clearing tty pointer in vcc_cleanup
vcc_cleanup() sets port->tty to NULL without holding port->lock, racing
with vcc_event() LDC callbacks that read port->tty under port->lock and
then use tty->port. This can cause a use-after-free when the callback
dereferences tty->port after cleanup has already destroyed and freed it. |
| Vulnerability in Oracle Essbase (component: Security). The supported version that is affected is 21.8.3.0.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via T3, IIOP to compromise Oracle Essbase. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Essbase accessible data as well as unauthorized read access to a subset of Oracle Essbase accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Essbase. CVSS 3.1 Base Score 5.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L). |

| In the Linux kernel, the following vulnerability has been resolved:
cxgb4/ch_ktls: disable softirqs around tid_list erases
chcr_ktls_cpl_act_open_rpl() inserts into tid_list from the receive path
using xa_insert_bh(). The array is shared by the adapter's connections
and initialized with XA_FLAGS_LOCK_BH. However, chcr_ktls_dev_del() and
the chcr_ktls_dev_add() error path use xa_erase(), which takes the XArray
lock without disabling softirqs.
When cleanup runs with softirqs enabled, a receive softirq for another
connection on the same CPU can interrupt the erase and spin on the lock
held by the interrupted task. Use xa_erase_bh() at both sites to match
the insertion path. |
| virtualenv is a tool for creating isolated virtual python environments. From 21.14.9 until 21.14.13, the bash bin/activate script can copy an attacker-controlled --prompt value into PS1 without escaping dollar signs or backticks when both promptvars and POSIX mode are disabled during activation. Re-enabling promptvars, running set -o posix, or starting an interactive child bash that inherits the exported PS1 can then expand command substitution in the stored VIRTUAL_ENV_PROMPT value and execute commands as the user who activates the environment. This issue is fixed in version 21.14.13. |
