Overview
Affected versions of this package are vulnerable to Stack-based Buffer Overflow via the SWF decompression. An attacker can cause a crash and disrupt service availability by sending specially crafted compressed data.
Note:
This is only exploitable if swf-decompression is enabled in the configuration.
Workaround
This vulnerability can be mitigated by disabling swf-decompression in the configuration file or by setting decompress-depth to less than half of the stack size if swf-decompression must be enabled.
