Security Advisory Description

Multiple integer overflows in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g allow remote attackers to cause a denial of service (heap memory corruption or NULL pointer dereference) or possibly have unspecified other impact via a long digit string that is mishandled by the (1) BN_dec2bn or (2) BN_hex2bn function, related to crypto/bn/bn.h and crypto/bn/bn_print.c. (CVE-2016-0797)

  • Customized iRules LX, iAppsLX applications, or custom monitors call external scripts that pass untrusted values to OpenSSL using the command line utilities (such as OpenSSL) or OpenSSL libraries via a language wrapper.
  • The user calls the OpenSSL command line utilities directly, and passes untrusted values as command line parameters
