CVE-2015-8790 is a medium-severity information disclosure vulnerability affecting libEBML versions prior to 1.3.3, including products like Matroska. It stems from an invalid memory access in the EbmlUnicodeString::UpdateFromUTF8 function, triggered by a crafted UTF-8 string, allowing attackers to potentially obtain sensitive information from process heap memory. The attack requires user interaction (UI:R) and can be executed over a network (AV:N), but has low impact on confidentiality (C:L) and no impact on integrity or availability. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
