minidlna: ReadyMedia (MiniDLNA) versions from 1.1.15 up to 1.3.2 is vulnerable to Buffer Overflow
CVE-2023-33476 is fixed in minidlna on 1 platform, first by minidlna 1.2.1+dfsg-1ubuntu0.18.04.1+esm1, released June 2, 2023. It is not reported as exploited. Patch Radar priority: Urgent.
ReadyMedia (MiniDLNA) versions from 1.1.15 up to 1.3.2 is vulnerable to Buffer Overflow. The vulnerability is caused by incorrect validation logic when handling HTTP requests using chunked transport encoding. This results in other code later using attacker-controlled chunk values that exceed the length of the allocated buffer, resulting in out-of-bounds read/write.
