CVE-2015-1591

The kamcmd administrative utility and default configuration in kamailio before version 4.3.0 use the /tmp/kamailio_ctl directory.

CVE-2013-7426 identifies an insecure handling of temporary files in kamailio 4.0.1, specifically concerning the /tmp/kamailio_fifo file. This may lead to unauthorized access to data.

A vulnerability was detected in Kamailio up to versions 6.0.7/6.1.3 in the isup_get_calling_party function of the file src/modules/sipt/ss7_parser.c in the sipt module. Manipulation of the length argument results in buffer overflow. The attack may be performed remotely.

A weakness in Kamailio up to 5.8.8/6.0.7/6.1.4/6.2.0-dev1 affects the shm_malloc function in src/modules/cdp/receiver.c of the CDP Diameter Receiver component. Manipulation leads to a heap-based buffer overflow. The attack can be remote, and the exploit is public. Upgrading to 6.0.8 resolves the issue.

An issue in kamailio v.6.1.1 and before allows a remote attacker to cause a denial of service via the ims_registrar_pcscf module, specifically the pcscf_save_pending/save_pending path and security-agreement parsing in sec_agree.c:parse_sec_agree().

A vulnerability in Kamailio version 6.1.1 and earlier allows a remote attacker to cause a denial of service via the IMS P-CSCF registration handling components.

A vulnerability in Kamailio up to 5.5.0/6.0.7 in the get_4bytes function of the cxdx_avp.c file in the AVP Handler component leads to an out-of-bounds read. The attack can be performed remotely, and the exploit is publicly disclosed.

Kamailio before versions 6.0.5 and 5.8.7 contains an out-of-bounds read vulnerability in the auth module. A specially crafted SIP packet can cause a process crash (DoS) after successful user authentication without a database backend.

In Kamailio (formerly OpenSER and SER) prior to versions 6.1.1, 6.0.6, and 5.8.8, an out-of-bounds access vulnerability exists in the core. A remote attacker can send a specially crafted TCP packet, causing a process crash (denial of service). This affects Kamailio instances with TCP or TLS listeners.
