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 CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L) Affected Products and Versions Enterprise Scanner 2.3 Remediation/Fixes Please contact support.
