Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Privilege escalation
EUVDB-ID: #VU7206
Risk: Low
CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7518
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows an local attacker to gain elevated privileges on the guest system.
The weakness exists due to debug exception error in syscall emulation. A attacker can gain system privileges.
Successful exploitation of the vulnerability results in privilege escalation.
MitigationUpdate the affected package to version: 3.16.43-2+deb8u5, 4.9.30-2+deb9u5

2) Out-of-bounds read
EUVDB-ID: #VU8008
Risk: Low
CVSSv3.1: 5.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:P/RL:U/RC:C]
CVE-ID: CVE-2017-7558
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information.
The weakness exists due to put-of-bounds read in the inet_diag_msg_sctpaddrs_fill(), inet_diag_msg_sctpladdrs_fill(), and sctp_get_sctp_info() functions in 'net/sctp/sctp_diag.c'. A local attacker can gain access to important data in portions of slab memory on the target system.
Update the affected package to version: 3.16.43-2+deb8u5, 4.9.30-2+deb9u5
