Security Bulletin
This security bulletin contains one medium risk vulnerability.
EUVDB-ID: #VU11163
Risk: Medium
CVSSv3.1: 8.3 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-7550
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to execute arbitrary code on the target system.
The weakness exists in the load_multiboot function due to out-of-bounds read or write. An adjacent attacker can load a kernel image during the boot process, which may cause the mh_load_end_addr address to be greater than the mh_bss_end_addr address, trigger memory corruption and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
Install update from vendor's website.
