Description
This security bulletin contains information about 5 vulnerabilities.
1) Information exposure (CVE-ID: CVE-2013-4299)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to read and manipulate data.
The vulnerability exists due to information exposure error within the area_location(), read_exceptions() and persistent_prepare_exception() functions in drivers/md/dm-snap-persistent.c. A remote user can read and manipulate data.
2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2013-4470)
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 Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is enabled, does not properly initialize certain data structures, which allows local users to cause a denial of service (memory corruption and system crash) or possibly gain privileges via a crafted application that uses the UDP_CORK option in a setsockopt system call and sends both short and long packets, related to the ip_ufo_append_data function in net/ipv4/ip_output.c and the ip6_ufo_append_data function in net/ipv6/ip6_output.c.
3) Buffer overflow (CVE-ID: CVE-2013-7027)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 7.1 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The ieee80211_radiotap_iterator_init function in net/wireless/radiotap.c in the Linux kernel before 3.11.7 does not check whether a frame contains any data outside of the header, which might allow attackers to cause a denial of service (buffer over-read) via a crafted header.
4) Resource management error (CVE-ID: CVE-2014-1444)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local #AU# to gain access to sensitive information.
The fst_get_iface function in drivers/net/wan/farsync.c in the Linux kernel before 3.11.7 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCWANDEV ioctl call.
5) Resource management error (CVE-ID: CVE-2014-1445)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The wanxl_ioctl function in drivers/net/wan/wanxl.c in the Linux kernel before 3.11.7 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via an ioctl call.
