"The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as
referenced in the USN-8122-1 advisory.

    Youngsung Kim discovered that PJSIP did not properly parse numeric header fields in SIP messages. A remote
    attacker could use this issue to cause PJSIP to crash, resulting in a denial of service, or possibly
    execute arbitrary code. This issue only affected Ubuntu 16.04 LTS. (CVE-2017-16872)

    Peter Koletzki discovered that PJSIP did not properly handle certain connection requests. A remote
    attacker could possibly use this issue to cause PJSIP to enter an unrecoverable state and reject further
    connections, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS. (CVE-2017-16875)

    Alfred Farrugia, Sandro Gauci, and Kevin Harwell discovered that PJSIP did not properly parse certain SDP
    messages. A remote attacker could possibly use this issue to cause PJSIP to crash, resulting in a denial
    of service. This issue only affected Ubuntu 16.04 LTS. (CVE-2018-1000098, CVE-2018-1000099)

    Lauri Vnsk discovered that PJSIP did not verify hostnames when reusing TLS connections. If a remote
    attacker were able to intercept communication, this flaw could possibly be exploited to view sensitive
    information. (CVE-2020-15260)

    It was discovered that PJSIP did not properly handle certain sequences of SDP messages. A remote attacker
    could possibly use this issue to cause PJSIP to crash, resulting in a denial of service. (CVE-2021-21375)

    It was discovered that the SSL socket implementation in PJSIP contained a race condition. A remote
    attacker could possibly use this issue to cause PJSIP to crash, resulting in a denial of service. This
    issue was only addressed in Ubuntu 18.04 LTS. (CVE-2021-32686)

    It was discovered that PJSIP did not properly parse certain STUN messages. A remote attacker could use
    this issue to cause PJSIP to crash, resulting in a denial of service, or possibly execute arbitrary code.
    (CVE-2021-37706)

    Uriya Yavnieli discovered that PJSIP did not properly manage memory under certain conditions. A remote
    attacker could use this issue to cause PJSIP to crash, resulting in a denial of service, or possibly
    execute arbitrary code. (CVE-2021-43299, CVE-2021-43300, CVE-2021-43301, CVE-2021-43302, CVE-2021-43303)

    It was discovered that PJSIP did not properly manage memory when processing ICE session credentials. A
    remote attacker could use this issue to cause PJSIP to crash, resulting in a denial of service, or
    possibly execute arbitrary code. (CVE-2026-25994)
