{"id":"USN-8122-1","summary":"pjproject vulnerabilities","details":"Youngsung Kim discovered that PJSIP did not properly parse numeric header\nfields in SIP messages. A remote attacker could use this issue to cause\nPJSIP to crash, resulting in a denial of service, or possibly execute\narbitrary code. This issue only affected Ubuntu 16.04 LTS. (CVE-2017-16872)\n\nPeter Koletzki discovered that PJSIP did not properly handle certain\nconnection requests. A remote attacker could possibly use this issue to\ncause PJSIP to enter an unrecoverable state and reject further connections,\nresulting in a denial of service. This issue only affected Ubuntu 16.04\nLTS. (CVE-2017-16875)\n\nAlfred Farrugia, Sandro Gauci, and Kevin Harwell discovered that PJSIP did\nnot properly parse certain SDP messages. A remote attacker could possibly\nuse this issue to cause PJSIP to crash, resulting in a denial of service.\nThis issue only affected Ubuntu 16.04 LTS. (CVE-2018-1000098,\nCVE-2018-1000099)\n\nLauri Vänskä discovered that PJSIP did not verify hostnames when reusing\nTLS connections. If a remote attacker were able to intercept communication,\nthis flaw could possibly be exploited to view sensitive information.\n(CVE-2020-15260)\n\nIt was discovered that PJSIP did not properly handle certain sequences of\nSDP messages. A remote attacker could possibly use this issue to cause\nPJSIP to crash, resulting in a denial of service. (CVE-2021-21375)\n\nIt was discovered that the SSL socket implementation in PJSIP contained a\nrace condition. A remote attacker could possibly use this issue to cause\nPJSIP to crash, resulting in a denial of service. This issue was only\naddressed in Ubuntu 18.04 LTS. (CVE-2021-32686)\n\nIt was discovered that PJSIP did not properly parse certain STUN messages.\nA remote attacker could use this issue to cause PJSIP to crash, resulting\nin a denial of service, or possibly execute arbitrary code.\n(CVE-2021-37706)\n\nUriya Yavnieli discovered that PJSIP did not properly manage memory under\ncertain conditions. A remote attacker could use this issue to cause PJSIP\nto crash, resulting in a denial of service, or possibly execute arbitrary\ncode. (CVE-2021-43299, CVE-2021-43300, CVE-2021-43301, CVE-2021-43302,\nCVE-2021-43303)\n\nIt was discovered that PJSIP did not properly manage memory when processing\nICE session credentials. A remote attacker could use this issue to cause\nPJSIP to crash, resulting in a denial of service, or possibly execute\narbitrary code.
