Vulnerability Details CVEID: CVE-2011-1071 DESCRIPTION: GNU C Library could allow a remote attacker to execute arbitrary code on the system, caused by an error in the fnmatch() function. By persuading the application into using the function, a remote attacker could exploit this vulnerability to corrupt the stack and execute arbitrary code on the system. CVSS Base Score: 6.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 65671 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:P) 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) Affected Products and Versions z/TPF Enterprise Edition Version 1.1 Remediation/Fixes +----------+----------------------+---------------+-------------------------------------+ |Product |VRMF |APAR |Remediation/First Fix | +----------+----------------------+---------------+-------------------------------------+ | | | |Apply the APAR, which is available | | | | |for download from the TPF Family | |z/TPF |1.1 |APAR PJ45634 |Product: Maintenance web page. | +----------+----------------------+---------------+-------------------------------------+ Workarounds and Mitigations None.
