The packet-reassembly implementation in Cisco IOS XE 3.13S and earlier allows remote attackers to cause a denial of service (CPU consumption or packet loss) via fragmented (1) IPv4 or (2) IPv6 packets that trigger ATTN-3-SYNC_TIMEOUT errors after reassembly failures, aka Bug ID CSCuo37957.
The print_option function in dhcp-common.c in dhcpcd through 6.9.1, as used in dhcp.c in dhcpcd 5.x in Android before 5.1 and other products, misinterprets the return value of the snprintf function, which allows remote DHCP servers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted message.
The get_option function in dhcp.c in dhcpcd before 6.2.0, as used in dhcpcd 5.x in Android before 5.1 and other products, does not validate the relationship between length fields and the amount of data, which allows remote DHCP servers to execute arbitrary code or cause a denial of service (memory corruption) via a large length value of an option in a DHCPACK message.
The kernel extension in Cisco AnyConnect Secure Mobility Client 4.0(2049) on OS X allows local users to cause a denial of service (panic) via vectors involving contiguous memory locations, aka Bug ID CSCut12255.
The LDAP implementation on the Cisco Web Security Appliance (WSA) 8.5.0-000, Email Security Appliance (ESA) 8.5.7-042, and Content Security Management Appliance (SMA) 8.3.6-048 does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate, aka Bug IDs CSCuo29561, CSCuv40466, and CSCuv40470.
