21
FAUCET Score

CVE-2016-2375 is an out-of-bounds read vulnerability in Pidgin's MXIT protocol handler, affecting various Pidgin and Debian/Ubuntu Linux distributions. This medium-severity flaw (CVSS 5.3) allows for memory disclosure if a server sends specially crafted MXIT contact information. While a remote attacker can exploit this with low complexity and no user interaction, the potential impact is limited to confidentiality. There is no evidence of active exploitation, public exploit code, or significant community discussion, though it did receive some media coverage.
