Detailsinfo

A vulnerability was found in ReadyMedia up to 1.3.3. It has been rated as critical. Affected by this issue is an unknown function of the component DFF File Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. CVE summarizes:

ReadyMedia (formerly MiniDLNA) versions 1.3.0 through 1.3.3 contain a stack-based buffer overflow vulnerability that allows remote attackers to corrupt stack memory by crafting a malicious DFF audio file with an oversized PROP chunk size value that is used unvalidated to allocate a variable-length stack array and read file data into it. Attackers can place a crafted DFF file in a directory monitored by ReadyMedia to trigger automatic parsing via inotify, achieving remote code execution on unprotected builds or denial of service on hardened builds with stack protections.
