<net-dns/avahi-0.6.10 is vulnerable to the following:

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2288
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2289

Didn't notice this as I bumped the ebuild to 0.6.10

sparc and x86, please test and stable - thanks

Does this run as root? If not, this is probably only B3

sparc stable.

------- Comment #3 From Joshua Jackson 2006-05-16 21:51:11 0000 ------- 
all done on x86 as well ^.^

Thx Joshua, but please don't close security bugs.

Time for GLSA decision. Impact is rather vague so I tend to vote NO.

SA 20022 http://secunia.com/advisories/20022  shows details on the impact.

i think the buffer overflow comes from these lines of code :
http://0pointer.de/cgi-bin/viewcvs.cgi/trunk/avahi-core/rr.c?rev=1209&view=diff&r1=1209&r2=1208&p1=trunk/avahi-core/rr.c&p2=/trunk/avahi-core/rr.c

Remote exec of code is serious, but in this case, the official advisory says it
is hardly remotely exploitable.
http://0pointer.de/cgi-bin/viewcvs.cgi/*checkout*/trunk/docs/NEWS?root=avahi
"We do not consider either of them major security threats. "
"The buffer overflow is hard to exploit remotely, only local users can
become the 'avahi' user. In addition the user is trapped inside a
chroot() environment (at least on Linux). "

Concerning the DoS issue (exploitable from a local network only), it is also
possible to DoS avahi with inconsistent data. So the DoS issue is not very
serious as for me.

I vote NO.

yet another no and closing. Of course, feel free to reopen if you disagree.
