Description Agostino Sarubbo gentoo-dev 2015-05-08 09:51:09 UTC
From ${URL} :

It was found that Wireshark crashes when processing (with "tshark -nr genbroad.snoop") a same file from the Wireshark wiki page:

wget '' -O genbroad.snoop

Additional details:

* crash reason: strlen() called on invalid pointer (value 0x56998680 == 1452902016)
* the function set_dnet_address at packet-dec-dnart.c:355
* it is called 4 times
* the 2nd time is the one when the value is set
* the variable is called addr in the context of /epan/dissectors/packet-dec-dnart.c:357, function set_dnet_address
* the variable is called pinfo->src->data in the upper frames
* in this function, this macro modifies the value:
wmem_strdup(pinfo->pool, addr));
* it should set paddr_tgt->data = addr, but the value gets garbled by the ctlq instruction:
|0x7ffff4d85522 dnet_address+50> callq 0x7ffff4b0d4b0 <wmem_strdup@plt>
|0x7ffff4d85527 dnet_address+55> cltq

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

As per the URL: 

This bug should not exist in Wireshark 1.12.x, for all values of x, as the change that introduced the call to wmem_strdup() in packet-dec-dnart.c also added an include of <epan/wmem/wmem.h>.


We only have 1.12 in tree so this is not vulnerable.

Added to an existing GLSA Request.
