Description
This security bulletin contains information about 6 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2013-1059)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows remote attackers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an auth_reply message that triggers an attempted build_request operation.
2) Resource management error (CVE-ID: CVE-2013-2148)
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 fill_event_metadata function in fs/notify/fanotify/fanotify_user.c in the Linux kernel through 3.9.4 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory via a read operation on the fanotify descriptor.
3) Information exposure (CVE-ID: CVE-2013-2164)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to information exposure error within the mmc_ioctl_cdrom_read_data() function in drivers/cdrom/cdrom.c. A local user can gain access to sensitive information.
4) Format string error (CVE-ID: CVE-2013-2851)
CWE-ID: CWE-134 - Use of Externally-Controlled Format String
CVSSv4: 7.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local #AU# to execute arbitrary code.
Format string vulnerability in the register_disk function in block/genhd.c in the Linux kernel through 3.9.4 allows local users to gain privileges by leveraging root access and writing format string specifiers to /sys/module/md_mod/parameters/new_array in order to create a crafted /dev/md device name.
5) Resource management error (CVE-ID: CVE-2013-4125)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: 8.2 [CVSS:4.0/AV:N/AC:L/AT:P/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 fib6_add_rt2node function in net/ipv6/ip6_fib.c in the IPv6 stack in the Linux kernel through 3.10.1 does not properly handle Router Advertisement (RA) messages in certain circumstances involving three routes that initially qualified for membership in an ECMP route set until a change occurred for one of the first two routes, which allows remote attackers to cause a denial of service (system crash) via a crafted sequence of messages.
6) Use-after-free (CVE-ID: CVE-2013-4127)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 6.9 [CVSS:4.0/AV:L/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 attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing vectors involving powering on a virtual machine. A local users can cause a denial of service (OOPS and system crash).
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
