Fixed In Version: sofia-sip 1.13.8
Doc Type: If docs needed, set a value
Doc Text:
An out-of-bound read flaw was found in sofia-sip's sip_method_d() function in sip_parser.c. An attacker can send a message with evil sdp to FreeSWITCH, which may cause crash. A crash is caused by #define MATCH(s, m) (strncmp(s, m, n = sizeof(m) - 1) == 0), this will make n bigger and trigger out-of-bound access when IS_NON_WS(s[n]).

Description TEJ RATHI 2022-06-02 08:38:34 UTC 
Prior to version 1.13.8, an attacker can send a message with evil sdp to FreeSWITCH, which may cause crash. This type of crash may be caused by `#define MATCH(s, m) (strncmp(s, m, n = sizeof(m) - 1) == 0)`, which will make `n` bigger and trigger out-of-bound access when `IS_NON_WS(s[n])`. Version 1.13.8 contains a patch for this issue.
