Description

OpenSSL through 1.0.2h incorrectly uses pointer arithmetic for heap-buffer boundary checks, which might allow remote attackers to cause a denial of service (integer overflow and application crash) or possibly have unspecified other impact by leveraging unexpected malloc behavior, related to s3_srvr.c, ssl_sess.c, and t1_lib.c.

Solution(s)

  • http-openssl-1_0_1-upgrade-1_0_1_u
  • http-openssl-1_0_2-upgrade-1_0_2_i
