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-2017-7482
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to buffer overflow. A local attacker can load a specially crafted Kerberos 5 ticket into a RxRPC key, trigger memory corruption and execute arbitrary code with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected package kernel.

2) Security restrictions bypass
EUVDB-ID: #VU7237
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-1000365,CVE-2017-7482
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to bypass security restrictions on the target system.
The weakness exists due to the failure to take the argument and environment strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size) into account when imposing a size restriction. A local attacker can bypass security limitation and perform unauthorized actions.
Successful exploitation of the vulnerability results in access to the system.
Update the affected package kernel.
