Security Bulletin
Summary
Multiple security vulnerabilities have been identified in glibc that is embedded in IBM FSM. This bulletin addresses these issues.
Vulnerability Details
CVEID: CVE-2016-1234
DESCRIPTION: glibc is vulnerable to a denial of service, caused by a stack-based buffer overflow within the glob implementation when GLOB_ALTDIRFUNC is used. A remote attacker could exploit this vulnerability using an overly long name to overflow a buffer and cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111311 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:L)
CVEID: CVE-2016-3706
DESCRIPTION: GNU C Library (glibc or libc6) is vulnerable to a denial of service, caused by a stack-based buffer overflow by the getaddrinfo function within sysdeps/posix/getaddrinfo.c. A remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/114123 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:L)
CVEID: CVE-2016-4429
DESCRIPTION: GNU C Library (glibc or libc6) is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the clntudp_call function within sunrpc/clnt_udp.c. By sending specially-crafted ICMP and UDP packets, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 7.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/114024 for the current score
CVSS Environmental Score*: Undefined
