SIPp through 3.7.7 Stack Buffer Overflow via createAuthHeader Algorithm Parameter

SIPp through 3.7.7 contains a stack buffer overflow vulnerability in createAuthHeader() when processing SIP authentication challenges with oversized algorithm parameters. A malicious SIP server can send a crafted 401 or 407 challenge to corrupt the stack and crash the client process.

SIPp through 3.7.7 Buffer Overflow via Oversized SIP Header Content

SIPp through 3.7.7 contains a buffer overflow vulnerability in the get_header() function in src/sip_parser.cpp when processing SIP messages with header content exceeding 20,490 bytes. Unauthenticated remote attackers can send crafted SIP messages with oversized headers to overflow the static buffer and crash the process.
