Summary
PJSIP: Stack buffer overflow in pjsip_auth_create_digest2()
Details

PJSIP is a free and open source multimedia communication library written in C. In 2.16 and earlier, a stack buffer overflow exists in pjsipauthcreatedigest2() in PJSIP when using pre-computed digest credentials (PJSIPCREDDATADIGEST). The function copies credential data using cred_info->data.slen as the length without an upper-bound check, which can overflow the fixed-size ha1 stack buffer (128 bytes) if data.slen exceeds the expected digest string length.
