sipXtapi CSeq field buffer overflow
| sipxtapi-cseq-bo (27681) |  High Risk |
Description:
The SIPfoundry sipXtapi library is vulnerable to a buffer overflow, caused by improper bounds checking of the "CSeq" field. By sending an overly long CSeq value, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the affected application.
Note: This vulnerability affects multiple products that utilize the sipXtapi library, including AOL Triton and multiple PingTel products.
