According to secunia advisory: https://secunia.com/advisories/47494/ :

Multiple vulnerabilities have been reported in Wireshark, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
compromise a user's system.

1) NULL pointer dereference errors when reading certain packet information can
be exploited to cause a crash.

2) An error within the RLC dissector can be exploited to cause a buffer
overflow via a specially crafted RLC packet capture file.

and according with upstream advisory:

1)http://www.wireshark.org/security/wnpa-sec-2012-01.html
Name: Multiple Wireshark file parser vulnerabilities
Description:
Laurent Butti discovered that Wireshark failed to properly check record sizes
for many packet capture file formats.
Impact:
It may be possible to make Wireshark crash by convincing someone to read a
malformed packet trace file.
Please use CVE-2012-0041 for this issue

There are 6 file format crashes here. In the interest of vendors, which dont always rebase to the newer version, would it be convenient to split these into 6 CVEs?

I doubt some older versions are affected by only some crashers.
