Description

This security bulletin contains information about 5 vulnerabilities.


1) Use-after-free (CVE-ID: CVE-2014-0131)

CWE-ID: CWE-416 - Use After Free

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 a use-after-free error within the skb_segment() function in net/core/skbuff.c. A local user can gain access to sensitive information.



2) Information exposure (CVE-ID: CVE-2014-3917)

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:L/SC:N/SI:N/SA:N]


The vulnerability allows a local user to read memory contents or crash the application.

kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2014-4014)

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

CVSSv4: 7.5 [CVSS:4.0/AV:N/AC:L/AT:P/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 capabilities implementation in the Linux kernel before 3.14.8 does not properly consider that namespaces are inapplicable to inodes, which allows local users to bypass intended chmod restrictions by first creating a user namespace, as demonstrated by setting the setgid bit on a file with group ownership of root.


4) Integer overflow (CVE-ID: CVE-2014-4611)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 8.4 [CVSS:4.0/AV:L/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 attacker to compromise the affected system.

the vulnerability exists due to integer overflow in the LZ4 algorithm implementation, as used in the lz4_uncompress function in lib/lz4/lz4_decompress.c in the Linux kernel on 32-bit platforms. A remote attacker create a specially crafted archive, trick the victim into opening it, trigger integer overflow and execute arbitrary code on the system.


5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2014-4943)

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 PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel through 3.15.6 allows local users to gain privileges by leveraging data-structure differences between an l2tp socket and an inet socket.
