CVE-2015-0261

Integer signedness error in the mobility_opt_print function in the IPv6 mobility printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (out-of-bounds read and crash) or possibly execute arbitrary code via a negative length value.

Several vulnerabilities have been discovered in tcpdump. These vulnerabilities might result in denial of service (application crash) or, potentially, execution of arbitrary code (CVE-2015-0261, CVE-2015-2153, CVE-2015-2154, CVE-2015-2155).

These are all security issues fixed in the tcpdump-4.7.4-3.4 package on the GA media of openSUSE Tumbleweed.

When running tcpdump, a remote unauthenticated user could have crashed the application or, potentially, execute arbitrary code by injecting crafted packages into the network.

The following vulnerabilities in protocol printers have been fixed:

* IPv6 mobility printer remote DoS (CVE-2015-0261, bnc#922220)
* Ethernet printer remote DoS (CVE-2015-2154, bnc#922222)
* PPP printer remote DoS (CVE-2014-9140, bnc#923142)

Integer signedness error in the mobility_opt_print function in the IPv6 mobility printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (out-of-bounds read and crash) or possibly execute arbitrary code via a negative length value.

It was discovered that tcpdump incorrectly handled printing certain packets. A remote attacker could use this issue to cause tcpdump to crash, resulting in a denial of service, or possibly execute arbitrary code.

In the default installation, attackers would be isolated by the tcpdump AppArmor profile.
