libvncserver vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in LibVNCServer.
Software Description: - libvncserver: vnc server library
Details:
Ramin Farajpour Cami discovered that LibVNCServer incorrectly handled certain malformed unix socket names. A remote attacker could exploit this with a crafted socket name, leading to a denial of service, or possibly execute arbitrary code. (CVE-2019-20839)
It was discovered that LibVNCServer did not properly access byte-aligned data. A remote attacker could possibly use this issue to cause LibVNCServer to crash, resulting in a denial of service. This issue only affected Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. (CVE-2019-20840)
Christian Beier discovered that LibVNCServer incorrectly handled anonymous TLS connections. A remote attacker could possibly use this issue to cause LibVNCServer to crash, resulting in a denial of service. This issue only affected Ubuntu 20.04 LTS. (CVE-2020-14396)
It was discovered that LibVNCServer incorrectly handled region clipping. A remote attacker could possibly use this issue to cause LibVNCServer to crash, resulting in a denial of service. (CVE-2020-14397)
It was discovered that LibVNCServer did not properly reset incorrectly terminated TCP connections. A remote attacker could possibly use this issue to cause an infinite loop, resulting in a denial of service. (CVE-2020-14398)
It was discovered that LibVNCServer did not properly access byte-aligned data. A remote attacker could possibly use this issue to cause LibVNCServer to crash, resulting in a denial of service. (CVE-2020-14399, CVE-2020-14400)
It was discovered that LibVNCServer incorrectly handled screen scaling on the server side. A remote attacker could use this issue to cause LibVNCServer to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-14401)
It was discovered that LibVNCServer incorrectly handled encodings. A remote attacker could use this issue to cause LibVNCServer to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-14402, CVE-2020-14403, CVE-2020-14404)
It was discovered that LibVNCServer incorrectly handled TextChat messages. A remote attacker could possibly use this issue to cause LibVNCServer to crash, resulting in a denial of service. (CVE-2020-14405)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04 LTS: libvncclient1 0.9.12+dfsg-9ubuntu0.2 libvncserver1 0.9.12+dfsg-9ubuntu0.2
Ubuntu 18.04 LTS: libvncclient1 0.9.11+dfsg-1ubuntu1.3 libvncserver1 0.9.11+dfsg-1ubuntu1.3
Ubuntu 16.04 LTS: libvncclient1 0.9.10+dfsg-3ubuntu0.16.04.5 libvncserver1 0.9.10+dfsg-3ubuntu0.16.04.5
After a standard system update you need to restart LibVNCServer applications to make all the necessary changes.

A remote attacker could exploit this\nwith a crafted socket name, leading to a denial of service, or possibly\nexecute arbitrary code. (CVE-2019-20839)\n\nIt was discovered that LibVNCServer did not properly access byte-aligned\ndata. A remote attacker could possibly use this issue to cause\nLibVNCServer to crash, resulting in a denial of service. This issue only\naffected Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. (CVE-2019-20840)\n\nChristian Beier discovered that LibVNCServer incorrectly handled anonymous\nTLS connections. A remote attacker could possibly use this issue to cause\nLibVNCServer to crash, resulting in a denial of service. This issue only\naffected Ubuntu 20.04 LTS. (CVE-2020-14396)\n\nIt was discovered that LibVNCServer incorrectly handled region clipping. A\nremote attacker could possibly use this issue to cause LibVNCServer to\ncrash, resulting in a denial of service. (CVE-2020-14397)\n\nIt was discovered that LibVNCServer did not properly reset incorrectly\nterminated TCP connections. A remote attacker could possibly use this\nissue to cause an infinite loop, resulting in a denial of service. \n(CVE-2020-14398)\n\nIt was discovered that LibVNCServer did not properly access byte-aligned\ndata. A remote attacker could possibly use this issue to cause\nLibVNCServer to crash, resulting in a denial of service. (CVE-2020-14399,\nCVE-2020-14400)\n\nIt was discovered that LibVNCServer incorrectly handled screen scaling on\nthe server side. A remote attacker could use this issue to cause\nLibVNCServer to crash, resulting in a denial of service, or possibly\nexecute arbitrary code. (CVE-2020-14401)\n\nIt was discovered that LibVNCServer incorrectly handled encodings. A\nremote attacker could use this issue to cause LibVNCServer to crash,\nresulting in a denial of service, or possibly execute arbitrary code. \n(CVE-2020-14402, CVE-2020-14403, CVE-2020-14404)\n\nIt was discovered that LibVNCServer incorrectly handled TextChat messages. \nA remote attacker could possibly use this issue to cause LibVNCServer to\ncrash, resulting in a denial of service. (CVE-2020-14405)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 20.04 LTS:\n libvncclient1 0.9.12+dfsg-9ubuntu0.2\n libvncserver1 0.9.12+dfsg-9ubuntu0.2\n\nUbuntu 18.04 LTS:\n libvncclient1 0.9.11+dfsg-1ubuntu1.3\n libvncserver1 0.9.11+dfsg-1ubuntu1.3\n\nUbuntu 16.04 LTS:\n libvncclient1 0.9.10+dfsg-3ubuntu0.16.04.5\n libvncserver1 0.9.10+dfsg-3ubuntu0.16.04.5\n\nAfter a standard system update you need to restart LibVNCServer\napplications to make all the necessary changes.
