Security Bulletin Document information Software version: 1.0.0 Operating system(s): Platform Independent Software edition: All Editions Reference #: 2012498 Modified date: 04 May 2018 Summary Open Source OpenSSL and GNU glibc are used by IBM Netezza Firmware Diagnostics. IBM Netezza Firmware Diagnostics Support Tools has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2017-3735 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error while parsing an IPAdressFamily extension in an X.509 certificate. An attacker could exploit this vulnerability to trigger an out-of-bounds read, resulting in an incorrect text display of the certificate. CVSS Base Score: 4.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 131047 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N) CVEID: CVE-2017-3736 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a carry propagation flaw in the x86_64 Montgomery squaring function bn_sqrx8x_internal(). An attacker with online access to an unpatched system could exploit this vulnerability to obtain information about the private key. CVSS Base Score: 5.9 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 134397 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N) CVEID: CVE-2017-15671 DESCRIPTION: GNU C Library is vulnerable to a denial of service, caused by a memory leak in the glob function in glob.c. A remote attacker could exploit this vulnerability to cause a denial of service condition. CVSS Base Score: 7.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 133909 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) CVEID: CVE-2017-15670 DESCRIPTION: GNU C Library is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the glob function in glob.c. By sending a specially-crafted string, a remote attacker could overflow a buffer and execute arbitrary code on the system.
