In short
A flaw in Sony XAV-AX5500's media file parser allows attackers to crash the device or run malicious code if a user opens a specially crafted WMV/ASF file. This happens because the device doesn't properly limit data when reading certain file structures, causing a buffer overflow.
Technical detail
Stack-based buffer overflow in WMV/ASF file parsing triggered by a malicious Extended Content Description Object. Attack vector is local/remote file delivery requiring user interaction; exploitation results in arbitrary code execution within the device context (CWE-121).
Summary generated and translated by AI from the official description.
Sony XAV-AX5500 WMV/ASF Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Sony XAV-AX5500 devices. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of WMV/ASF files. A crafted Extended Content Description Object in a WMV media file can trigger an overflow of a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device.
