Security Bulletin

Summary

Several security vulnerabilities have been found in glibc module of IBM
Security Proventia Network Enterprise Scanner.

Vulnerability Details

CVEID: CVE-2014-9761
DESCRIPTION: GNU C Library (glibc) is vulnerable to a stack-based buffer
overflow, caused by improper bounds checking by the nan function. By
sending an overly long string, a remote attacker could overflow a buffer
and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 5.6
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111085 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2015-8778
DESCRIPTION: GNU C Library (glibc) could allow a remote attacker to execute
arbitrary code on the system, caused by an integer overflow in hcreate
and hcreate_r. An attacker could exploit this vulnerability to trigger
an out-of-bound memory access and execute arbitrary code on the system or
cause the application to crash.
CVSS Base Score: 5.6
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111086 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2015-8779
DESCRIPTION: GNU C Library (glibc) is vulnerable to a stack-based buffer
overflow, caused by improper bounds checking by the catopen function. By
sending an overly long string, a remote attacker could overflow a buffer
and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 5.6
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111087 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2015-1781
DESCRIPTION: GNU C Library (glibc) is vulnerable to a buffer overflow,
caused by improper bounds checking by the gethostbyname_r() and other
related functions. By sending a specially-crafted argument, a remote
attacker could overflow a buffer and execute arbitrary code on the system
elevated privileges or cause the application to crash.
CVSS Base Score: 5.1
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/102500 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:P/A:P)

CVEID: CVE-2015-5229
DESCRIPTION: GNU C Library (glibc) is vulnerable to a denial of service,
caused by the return of memory areas containing non-zero bytes by the
calloc implementation. A remote attacker could exploit this vulnerability
to cause the application to crash or hang.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/110711 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2015-8776
DESCRIPTION: GNU C Library (glibc) is vulnerable to a denial of service. By
passing out-of-range time values to the strftime function, a remote attacker
could exploit this vulnerability to cause a segmentation fault or obtain
sensitive information.
CVSS Base Score: 6.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/110675 for the
current score
