The default configuration of the IPsec IKE peer listener in F5 BIG-IP LTM, Analytics, APM, ASM, and Link Controller 11.2.1 before HF16, 11.4.x, 11.5.x before 11.5.4 HF2, 11.6.x before 11.6.1, and 12.x before 12.0.0 HF2; BIG-IP AAM, AFM, and PEM 11.4.x, 11.5.x before 11.5.4 HF2, 11.6.x before 11.6.1, and 12.x before 12.0.0 HF2; BIG-IP DNS 12.x before 12.0.0 HF2; BIG-IP Edge Gateway, WebAccelerator, and WOM 11.2.1 before HF16; BIG-IP GTM 11.2.1 before HF16, 11.4.x, 11.5.x before 11.5.4 HF2, and 11.6.x before 11.6.1; and BIG-IP PSM 11.4.0 through 11.4.1 improperly enables the anonymous IPsec IKE peer configuration object, which allows remote attackers to establish an IKE Phase 1 negotiation and possibly conduct brute-force attacks against Phase 2 negotiations via unspecified vectors.

F5 BIG-IP before 12.0.0 HF3 allows remote authenticated users to modify the account configuration of users with the Resource Administration role and gain privilege via a crafted external Extended Application Verification (EAV) monitor script.

Virtual servers in F5 BIG-IP 11.5.4, when SSL profiles are enabled, allow remote attackers to cause a denial of service (resource consumption and Traffic Management Microkernel restart) via an SSL alert during the handshake.

F5 BIG-IP LTM, AFM, Analytics, APM, ASM, Link Controller, and PEM 11.3.x, 11.4.x before 11.4.1 build 685-HF10, 11.5.1 before build 10.104.180, 11.5.2 before 11.5.4 build 0.1.256, 11.6.0 before build 6.204.442, and 12.0.0 before build 1.14.628; BIG-IP AAM 11.4.x before 11.4.1 build 685-HF10, 11.5.1 before build 10.104.180, 11.5.2 before 11.5.4 build 0.1.256, 11.6.0 before build 6.204.442, and 12.0.0 before build 1.14.628; BIG-IP DNS 12.0.0 before build 1.14.628; BIG-IP Edge Gateway, WebAccelerator, and WOM 11.3.0; BIG-IP GTM 11.3.x, 11.4.x before 11.4.1 build 685-HF10, 11.5.1 before build 10.104.180, 11.5.2 before 11.5.4 build 0.1.256, and 11.6.0 before build 6.204.442; BIG-IP PSM 11.3.x and 11.4.x before 11.4.1 build 685-HF10; BIG-IQ Cloud, Device, and Security 4.2.0 through 4.5.0; and BIG-IQ ADC 4.5.0 do not properly regenerate certificates and keys when deploying cloud images in Amazon Web Services (AWS), Azure or Verizon cloud services environments, which allows attackers to obtain sensitive information or cause a denial of service (disruption) by leveraging a target instance configuration.

racoon/gssapi.c in IPsec-Tools 0.8.2 allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon crash) via a series of crafted UDP requests.

The rd_build_device_space function in drivers/target/target_core_rd.c in the Linux kernel before 3.14 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from ramdisk_mcp memory by leveraging access to a SCSI initiator.
