Security Bulletin: PowerKVM is affected by glibc vulnerabilities (Multiple CVEs)

Summary

PowerKVM is affected by multiple glibc vulnerabilities.

Vulnerability Details

CVEID: CVE-2014-6040**
DESCRIPTION:** The GNU C Library (glibc) is vulnerable to a denial of service, caused by the improper validation of input by the iconv() function when converting IBM933, IBM935, IBM937, IBM939 or IBM1364 encoded data to UTF-8. An attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/95616 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2014-8121**
DESCRIPTION:** GNU C Library (glibc) is vulnerable to a denial of service, caused by the failure to properly check if a file is open by DB_LOOKUP in nss_files/files-XXX.c in the Name Service Switch (NSS). By performing a look-up on a database while iterating over it, an attacker could exploit this vulnerability to cause the application to enter into an infinite loop.
