CVE-2022-2867

La utilidad tiffcrop de libtiff presenta un desbordamiento de uint32_t que puede conllevar a una lectura y escritura fuera de límites. Un atacante que suministre un archivo diseñado a tiffcrop (probablemente por medio de engañar a un usuario para que ejecute tiffcrop en él con determinados parámetros) podría causar un bloqueo o, en algunos casos, una explotación adicional.

A flaw was found in libtiff's tiffcrop utility that has a uint32_t underflow that can lead to an out-of-bounds read and write. This flaw allows an attacker who supplies a crafted file to tiffcrop (likely via tricking a user to run tiffcrop on it with certain parameters)to cause a crash or, in some cases, further exploitation.

Juraj Somorovsky, Marcel Maehren, Nurullah Erinola, and Robert Merget discovered that the DTLS implementation in the JSSE subsystem of OpenJDK did not properly restrict handshake initiation requests from clients. A remote attacker could possibly use this to cause a denial of service. Markus Loewe discovered that the Java Sound subsystem in OpenJDK did not properly validate the origin of a Soundbank. An attacker could use this to specially craft an untrusted Java application or applet that could load a Soundbank from an attacker controlled remote URL.
