[Secure-testing-team] Bug#488630: linuxdcpp: Two remote DoS

[Steffen Joeris]

Package: linuxdcpp
Version: 1.0.1-1
Severity: grave
Tags: security, patch
Justification: user security hole

Hi

The following email came over one of the security lists:

Hey,

Linux DC++ (linuxdcpp) is a Direct Connect client based on the same 
client code as DC++, so it is vulnerable to the recently reported

[1] NULL pointer dereference remote DoS via partial file list requests
http://secunia.com/advisories/30812/
http://sourceforge.net/project/shownotes.php?release_id=608612&group_id=40287
https://bugs.launchpad.net/dcplusplus/+bug/238333 [Can't view]

Patch for linuxdcpp:
http://cvs.berlios.de/cgi-bin/viewcvs.cgi/linuxdcpp/linuxdcpp/client/ShareManager.cpp.diff?r1=1.14&r2=1.15&sortby=date

[2] Empty message Remote DoS
When an attacker sends an empty message, he can cause the client to 
abort with "std::out_of_range" in substr().

Patch for linuxdcpp:

The patchsets are not included in the current sid version. CVE ids for both DoS
are pending.
Please also upload with high urgency, so that the package hits testing soon.

Cheers
