Description
This security bulletin contains information about 2 vulnerabilities.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2013-1959)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: 2.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
kernel/user_namespace.c in the Linux kernel before 3.8.9 does not have appropriate capability requirements for the uid_map and gid_map files, which allows local users to gain privileges by opening a file within an unprivileged process and then modifying the file within a privileged process.
2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2013-1979)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The scm_set_cred function in include/net/scm.h in the Linux kernel before 3.8.11 uses incorrect uid and gid values during credentials passing, which allows local users to gain privileges via a crafted application.
