I have a number of songs in my Music library that display incorrect duration values, and so play only partially in Clementine. In Banshee and some other players they show different duration values and sometimes play the full song.
Is there a way to fix this without having to "re-encode" the song?
MP3 Diags can fix incorrect durations (and other errors). It is open source and in the repositories. It is a GUI Tool.
Installation
sudo apt-get install mp3diags mp3diags-doc
Another option is MP3val, which can be used either via commandline or via GUI:
Installation
sudo apt-get install mp3val
Usage example
mp3val damaged.mp3 -f -t
-f: fix errors,
-t: keep original timestamp
If you don't want to install anything new, try with ffmpeg:
ffmpeg -i file_orig.mp3 -acodec copy file_fixed.mp3
Aside from the VBR headers not matching the actual audio (which you would use mp3val to correct, as mentioned in the other answer), another reason this can be caused is by an MP3 file having ID3 tag that has an incorrect value for the TLEN tag. You can fix this using the mid3v2 tool from the mutagen package to remove the tag (apparently its optional):
$ mid3v2 --delete-frames=TLEN filename.mp3
The music player Quodlibet also has a convenient "Fix MP3 Duration" plugin you can use to do this.

mp3check worked perfect for me also with wildcards.
sudo apt-get install mp3check
mp3check {filename or wildcard} --cut-junk-start --cut-junk-end --fix-headers
