An issue was discovered in the libsofia-sip fork in drachtio-server before 0.8.20. It allows remote attackers to cause a denial of service (daemon crash) via a crafted UDP message that leads to a failure of the libsofia-sip-ua/tport/tport.c self assertion.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5410 advisory.

  - Sofia-SIP is an open-source Session Initiation Protocol (SIP) User-Agent library. 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.
    (CVE-2022-31001)

  - Sofia-SIP is an open-source Session Initiation Protocol (SIP) User-Agent library. Prior to version 1.13.8,     an attacker can send a message with evil sdp to FreeSWITCH, which may cause a crash. This type of crash     may be caused by a URL ending with `%`. Version 1.13.8 contains a patch for this issue. (CVE-2022-31002)

  - Sofia-SIP is an open-source Session Initiation Protocol (SIP) User-Agent library. Prior to version 1.13.8,     when parsing each line of a sdp message, `rest = record + 2` will access the memory behind `\0` and cause     an out-of-bounds write. An attacker can send a message with evil sdp to FreeSWITCH, causing a crash or     more serious consequence, such as remote code execution. Version 1.13.8 contains a patch for this issue.
    (CVE-2022-31003)

  - An issue was discovered in the libsofia-sip fork in drachtio-server before 0.8.20. It allows remote     attackers to cause a denial of service (daemon crash) via a crafted UDP message that leads to a failure of     the libsofia-sip-ua/tport/tport.c self assertion. (CVE-2022-47516)

  - Sofia-SIP is an open-source SIP User-Agent library, compliant with the IETF RFC3261 specification. In     affected versions Sofia-SIP **lacks both message length and attributes length checks** when it handles     STUN packets, leading to controllable heap-over-flow. For example, in stun_parse_attribute(), after we get     the attribute's type and length value, the length will be used directly to copy from the heap, regardless     of the message's left size. Since network users control the overflowed length, and the data is written to     heap chunks later, attackers may achieve remote code execution by heap grooming or other exploitation     methods. The bug was introduced 16 years ago in sofia-sip 1.12.4 (plus some patches through 12/21/2006) to     in tree libs with git-svn-id: http://svn.freeswitch.org/svn/freeswitch/trunk@3774     d0543943-73ff-0310-b7d9-9358b9ac24b2. Users are advised to upgrade. There are no known workarounds for     this vulnerability. (CVE-2023-22741)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5932-1 advisory.

    It was discovered that Sofia-SIP incorrectly handled specially crafted SDP packets. A remote attacker     could use this issue to cause applications using Sofia-SIP to crash, leading to a denial of service, or     possibly execute arbitrary code. This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, Ubuntu 20.04     LTS and Ubuntu 22.04 LTS. (CVE-2022-31001, CVE-2022-31002, CVE-2022-31003)
