Service interruption via malformed multipart headers
Published Oct 11, 2022 · Updated May 20, 2025
Integer overflow in GNU oSIP 5.3.0 allows remote attackers to cause a service interrupt via crafted SIP multipart headers. The osip_body_parse_header parser mishandles an invalid line-ending result from its CRLF search in multipart bodies, allowing arithmetic state to reach the overflow path. Exploitation requires a victim application to parse attacker-controlled SIP data and can produce a denial of service without confidentiality or integrity impact.
