Flac123 Stack Overflow in Comment Parsing
------------------------------------------------------------------------
SUMMARY
flac123, also known as flac-tools, is vulnerable to a buffer overflow in
vorbis comment parsing. This allows for the execution of arbitrary code.
DETAILS
Vulnerable Systems:
* flac123 version 0.0.9
Immune Systems:
* flac123 version 0.0.10
The function local__vcentry_parse_value() in vorbiscomment.c does not
correctly handle a long value_length, causing it to overflow the buffer
"dest" during memcpy().
