Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Use-after-free error
EUVDB-ID: #VU10678
Risk: Medium
CVSSv3.1: 7.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-18017
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition no the target system.
The weakness exists in the tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel due to use-after-free error. A remote attacker can leverage the presence of xt_TCPMSS in an iptables action, trigger memory corruption and cause the system to crash.

2) Information disclosure
EUVDB-ID: #VU9769
Risk: Low
CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-17449
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists due to the __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel, when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net namespace. A local attacker can leverage the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink
activity on the system and read arbitrary files.
