The vulnerability could be exploited in allowing a local user to\r\nelevate their privilege.\r\n\r\nReferences:\r\n\r\nCVE-2015-2126\r\n\r\nSSRT102094\r\n\r\nSUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.\r\n\r\nHP-UX 11iv2, 11iv3\r\n\r\nBACKGROUND\r\n\r\nCVSS 2.0 Base Metrics\r\n===========================================================\r\n Reference Base Vector Base Score\r\nCVE-2015-2126 (AV:L/AC:L/Au:S/C:C/I:C/A:C) 6.8\r\n===========================================================\r\n Information on CVSS is documented\r\n in HP Customer Notice: HPSN-2008-002\r\n\r\nRESOLUTION\r\n\r\nHP has provided the following work around for HP-UX 11iv2 & 11iv3.\r\n\r\nA non-root user on the HP-UX 11iv2 & 11iv3 system can exploit the "pppoec"\r\nutility due to its access permissions.\r\n\r\nUntil the official fix for the issue is released, HP recommends the following\r\nworkaround be applied to avoid any misuse of the pppoec utility.\r\n\r\nMake sure that the /usr/bin/pppoec is executed by root user. Unset the "s"\r\nbit of the "pppoec" utility.\r\n\r\nThe command used to unset the "s" bit is as follows.\r\n# /usr/bin/chmod u-s /usr/bin/pppoec\r\n\r\nNote: On HP-UX 11iv2, /usr/bin/pppoec utility will not be available by\r\ndefault. Hence take above action only if /usr/bin/pppoec file is available.\r\n\r\nMANUAL ACTIONS: # /usr/bin/chmod u-s /usr/bin/pppoec\r\n\r\nHISTORY\r\nVersion:1 (rev.1) - 26 June 2015 Initial release\r\n\r\nThird Party Security Patches: Third party security patches that are to be\r\ninstalled on systems running HP software products should be applied in\r\naccordance with the customer's patch management policy.\r\n\r\nSupport: For issues about implementing the recommendations of this Security\r\nBulletin, contact normal HP Services support channel.
