Description

This security bulletin contains information about 6 vulnerabilities.


1) Concurrent execution using shared resource with improper synchronization ('race condition') (CVE-ID: CVE-2014-9710)

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

CVSSv4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to execute arbitrary code.

The vulnerability exists due to concurrent execution using shared resource with improper synchronization ('race condition') error. A local user can execute arbitrary code.


2) Race condition (CVE-ID: CVE-2015-1420)

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

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.

Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function.


3) Integer overflow (CVE-ID: CVE-2015-4001)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 8.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The vulnerability exists due to integer overflow error within the oz_hcd_pd_reset() and oz_hcd_get_desc_cnf() functions in drivers/staging/ozwpan/ozhcd.c. A remote non-authenticated attacker can read and manipulate data.


4) Memory corruption (CVE-ID: CVE-2015-4002)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: 8.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The vulnerability exists due to memory corruption error within the oz_usb_rx() function in drivers/staging/ozwpan/ozusbsvc1.c. A remote non-authenticated attacker can read and manipulate data.


5) Division by zero (CVE-ID: CVE-2015-4003)

CWE-ID: CWE-369 - Divide By Zero

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 a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a division by zero error within the oz_usb_handle_ep_data() function in drivers/staging/ozwpan/ozusbsvc1.c. A remote non-authenticated attacker can perform a denial of service (DoS) attack.


6) Integer overflow (CVE-ID: CVE-2015-4167)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to integer overflow within the fs/udf/inode.c. A local user can perform a denial of service (DoS) attack.
