security bulletin CVE-2015-1277

Chrome: use after free via ui-AXTree-Unserialize

Synthesis of the vulnerability

An attacker can force the usage of a freed memory area in ui::AXTree::Unserialize() of Chrome, in order to trigger a denial of service, and possibly to run code.
Severity: 3/4.
Creation date: 21/07/2015.
Identifiers: CVE-2015-1277, DSA-3315-1, RHSA-2015:1499-01, USN-2677-1, VIGILANCE-VUL-17463.
Full Vigil@nce bulletin... (Free trial)

Description of the vulnerability

The Chrome browser can load an HTML page containing JavaScript code processing style data.

However, the ui::AXTree::Unserialize() function frees a memory area before reusing it.

An attacker can therefore force the usage of a freed memory area in ui::AXTree::Unserialize() of Chrome, in order to trigger a denial of service, and possibly to run code.

weakness alert CVE-2015-5600

OpenSSH: bypassing MaxAuthTries via KbdInteractiveDevices

Synthesis of the vulnerability

An attacker can bypass the MaxAuthTries directive of OpenSSH, in order to perform a brute force attack.
Severity: 2/4.
Creation date: 20/07/2015.
Identifiers: 9010048, bulletinoct2015, CERTFR-2015-AVI-431, CERTFR-2017-AVI-012, CERTFR-2017-AVI-022, cpujul2018, CVE-2015-5600, DLA-1500-1, DLA-1500-2, FEDORA-2015-11981, FEDORA-2015-13469, FreeBSD-SA-15:16.openssh, JSA10697, JSA10774, JSA10840, K17113, NTAP-20151106-0001, RHSA-2015:2088-06, RHSA-2016:0466-01, SB10157, SB10164, SOL17113, SUSE-SU-2015:1581-1, SYMSA1337, USN-2710-1, USN-2710-2, VIGILANCE-VUL-17455.
Full Vigil@nce bulletin... (Free trial)

Description of the vulnerability

The OpenSSH server uses the MaxAuthTries configuration directive to define the maximal number of authentication trials during a session.

The OpenSSH client uses the KbdInteractiveDevices option to define the list of authentication methods.

However, if the client uses "KbdInteractiveDevices=pam,pam,pam,etc.", the number of MaxAuthTries is multiplied. The limit thus becomes LoginGraceTime (10 minutes by default).

An attacker can therefore bypass the MaxAuthTries directive of OpenSSH, in order to perform a brute force attack.
