Multiple vulnerabilities have been reported in Ethereal, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.

1) Boundary errors in the "dissect_a11_radius()" function in "packet-3g-a11.c" used for RADIUS authentication dissection can be exploited to cause a stack-based buffer overflow by sending a specially crafted CDMA2000 A11 packet.

This vulnerability affects versions 0.10.3 through 0.10.9.

2) A boundary error in the "dissect_pdus()" function of the IAPP dissector can be exploited to cause a buffer overflow via a specially crafted packet.

This vulnerability affects versions 0.9.1 through 0.10.9.

3) A boundary error in the Etheric dissector can be exploited to cause a buffer overflow via a specially crafted packet.

This vulnerability affects versions 0.10.7 through 0.10.9.

4) An unspecified error in the GPRS-LLC dissector can be exploited to cause a crash when the "ignore cipher bit" option is enabled.

This vulnerability affects versions 0.10.7 through 0.10.9.

5) An unspecified error in the JXTA dissector can be exploited to crash Ethereal.

This vulnerability affects version 0.10.9.

6) An unspecified error in the sFlow dissector can be exploited to crash Ethereal.

This vulnerability affects versions 0.9.14 through 0.10.9.

Successful exploitation of the vulnerabilities crashes Ethereal and some may allow execution of arbitrary code.

Solution
Update to version 0.10.10.
