The find_ifcfg_path function in netcf before 0.2.7 might allow attackers to cause a denial of service (application crash) via vectors involving augeas path expressions.

An issue was discovered in dns.c in HAProxy through 1.8.14. In the case of a compressed pointer, a crafted packet can trigger infinite recursion by making the pointer point to itself, or create a long chain of valid pointers resulting in stack exhaustion.

A flaw was found in the way Ceph Object Gateway would process cross-origin HTTP requests if the CORS policy was set to allow origin on a bucket. A remote unauthenticated attacker could use this flaw to cause denial of service by sending a specially-crafted cross-origin HTTP request. Ceph branches 1.3.x and 2.x are affected.

In dnsmasq before 2.78, if the DNS packet size does not match the expected size, the size parameter in a memset call gets a negative value. As it is an unsigned value, memset ends up writing up to 0xffffffff zero's (0xffffffffffffffff in 64 bit platforms), making dnsmasq crash.

A vulnerability was discovered in SPICE before 0.13.90 in the server's protocol handling. An attacker able to connect to the SPICE server could send crafted messages which would cause the process to crash.

The Generic Receive Offload (GRO) implementation in the Linux kernel 2.6.18 on Red Hat Enterprise Linux 5 and 2.6.32 on Red Hat Enterprise Linux 6, as used in Red Hat Enterprise Virtualization (RHEV) Hypervisor and other products, allows remote attackers to cause a denial of service via crafted VLAN packets that are processed by the napi_reuse_skb function, leading to (1) a memory leak or (2) memory corruption, a different vulnerability than CVE-2011-1478.

The SPICE Firefox plug-in (spice-xpi) 2.4, 2.3, 2.2, and possibly other versions allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to (1) plugin/nsScriptablePeer.cpp and (2) plugin/plugin.cpp, which trigger multiple uses of an uninitialized pointer.

A memory leak flaw was found in Libtiff's tiffcrop utility. This issue occurs when tiffcrop operates on a TIFF image file, allowing an attacker to pass a crafted TIFF image file to tiffcrop utility, which causes this memory leak issue, resulting an application crash, eventually leading to a denial of service.

Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB device or smart card to manipulate responses to APDUs. This manipulation can potentially allow compromise key generation, certificate loading, and other card management operations during enrollment.
