An issue was discovered in rust-ffmpeg 0.3.0 (after comit 5ac0527) An integer overflow vulnerability in the Vector::new constructor function allows an attacker to cause a denial of service via a null pointer dereference. The vulnerability stems from an unchecked cast of a usize parameter to c_int, which can result in a negative value being passed to the underlying C function sws_allocVec().Show less

An issue was discovered in rust-ffmpeg 0.3.0 (after comit 5ac0527) A null pointer dereference vulnerability in the input() constructor function allows an attacker to cause a denial of service. The vulnerability is triggered when the avio_alloc_context() call fails and returns NULL, which is then stored and later dereferenced by the Io struct's Drop implementation.Show less

An issue was discovered in rust-ffmpeg 0.3.0 (after comit 5ac0527) Null pointer dereference vulnerability in the name() method allows an attacker to cause a denial of service. The vulnerability exists because the method fails to check for a NULL return value from the av_get_sample_fmt_name() C function, which can be triggered by providing an unrecognized sample format.Show less

If a DHCPv4 client sends a request with some specific options, and Kea fails to find an appropriate subnet for the client, the `kea-dhcp4` process will abort with an assertion failure. This happens only if the client request is unicast directly to Kea; broadcast messages do not cause the problem. This issue affects Kea versions 2.7.1 through 2.7.9, 3.0.0, and 3.1.0.Show less
