Description

This security bulletin contains information about 1 vulnerability.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2011-2527)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The change_process_uid function in os-posix.c in Qemu 0.14.0 and earlier does not properly drop group privileges when the -runas option is used, which allows local guest users to access restricted files on the host.


Remediation
