Summary
IBM Security Virtual Server Protection for VMware is affected by
vulnerabilities found in GNU glibc.
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-2015-1781
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
