The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4335-1 advisory.

    Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of     service, obtain sensitive information, bypass security restrictions, bypass same-origin restrictions,     conduct cross-site scripting (XSS) attacks, or execute arbitrary code. (CVE-2019-11757, CVE-2019-11758,     CVE-2019-11759, CVE-2019-11760, CVE-2019-11761, CVE-2019-11762, CVE-2019-11763, CVE-2019-11764,     CVE-2019-17005, CVE-2019-17008, CVE-2019-17010, CVE-2019-17011, CVE-2019-17012, CVE-2019-17016,     CVE-2019-17017, CVE-2019-17022, CVE-2019-17024, CVE-2019-17026, CVE-2019-20503, CVE-2020-6798,     CVE-2020-6800, CVE-2020-6805, CVE-2020-6806, CVE-2020-6807, CVE-2020-6812, CVE-2020-6814, CVE-2020-6819,     CVE-2020-6820, CVE-2020-6821, CVE-2020-6825)

    It was discovered that NSS incorrectly handled certain memory operations. A remote attacker could     potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2019-11745)

    It was discovered that a specially crafted S/MIME message with an inner encryption layer could be     displayed as having a valid signature in some circumstances, even if the signer had no access to the     encrypted message. An attacker could potentially exploit this to spoof the message author.
    (CVE-2019-11755)

    A heap overflow was discovered in the expat library in Thunderbird. If a user were tricked in to opening a     specially crafted message, an attacker could potentially exploit this to cause a denial of service, or     execute arbitrary code. (CVE-2019-15903)

    It was discovered that Message ID calculation was based on uninitialized data. An attacker could     potentially exploit this to obtain sensitive information. (CVE-2020-6792)

    Mutiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted message, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information, or execute arbitrary code. (CVE-2020-6793, CVE-2020-6795, CVE-2020-6822)

    It was discovered that if a user saved passwords before Thunderbird 60 and then later set a primary     password, an unencrypted copy of these passwords would still be accessible. A local user could exploit     this to obtain sensitive information. (CVE-2020-6794)

    It was discovered that the Devtools Copy as cURL feature did not fully escape website-controlled     data. If a user were tricked in to using the Copy as cURL feature to copy and paste a command with     specially crafted data in to a terminal, an attacker could potentially exploit this to execute arbitrary     commands via command injection. (CVE-2020-6811)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2019:14260-1 advisory.

  - When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the     block size, a small out of bounds write could occur. This could have caused heap corruption and a     potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-11745)

  - Inappropriate implementation in WebRTC in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to     potentially exploit heap corruption via a crafted HTML page. (CVE-2019-13722)

  - The plain text serializer used a fixed-size array for the number of  elements it could process;
    however it was possible to overflow the static-sized array leading to memory corruption and a potentially     exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
    (CVE-2019-17005)

  - When using nested workers, a use-after-free could occur during worker destruction. This resulted in a     potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-17008)

  - When running, the updater service wrote status and log files to an unrestricted location; potentially     allowing an unprivileged process to locate and exploit a vulnerability in file handling in the updater     service. *Note: This attack requires local system access and only affects Windows. Other operating systems     are not affected.*. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
    (CVE-2019-17009)

  - Under certain conditions, when checking the Resist Fingerprinting preference during device orientation     checks, a race condition could have caused a use-after-free and a potentially exploitable crash. This     vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. (CVE-2019-17010)

  - Under certain conditions, when retrieving a document from a DocShell in the antitracking code, a race     condition could cause a use-after-free condition and a potentially exploitable crash. This vulnerability     affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. (CVE-2019-17011)

  - Mozilla developers reported memory safety bugs present in Firefox 70 and Firefox ESR 68.2. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort some of these could have     been exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3,     and Firefox < 71. (CVE-2019-17012)

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

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4203-1 advisory.

    It was discovered that NSS incorrectly handled certain memory operations. A remote attacker could use this     issue to cause NSS to crash, resulting in a denial of service, or possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

A vulnerability has been discovered in nss, the Mozilla Network Security Service library. An out-of-bounds write can occur when passing an output buffer smaller than the block size to NSC_EncryptUpdate.

For Debian 8 'Jessie', this problem has been fixed in version 2:3.26-1+debu8u7.

We recommend that you upgrade your nss packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has nss packages installed that are affected by multiple vulnerabilities:

  - Empty or malformed p256-ECDH public keys may trigger a     segmentation fault due values being improperly sanitized     before being copied into memory and used. This     vulnerability affects Firefox ESR < 60.8, Firefox < 68,     and Thunderbird < 60.8. (CVE-2019-11729)

  - When encrypting with a block cipher, if a call to     NSC_EncryptUpdate was made with data smaller than the     block size, a small out of bounds write could occur.
    This could have caused heap corruption and a potentially     exploitable crash. This vulnerability affects     Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox <     71. (CVE-2019-11745)

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

The version of nss installed on the remote host is prior to 3.44.0-7. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1384 advisory.

    A heap-based buffer overflow was found in the NSC_EncryptUpdate() function in Mozilla nss. A remote     attacker could trigger this flaw via SRTP encrypt or decrypt operations, to execute arbitrary code with     the permissions of the user running the application (compiled with nss). While the attack complexity is     high, the impact to confidentiality, integrity, and availability are high as well. (CVE-2019-11745)

    Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly     sanitized before being copied into memory and used. This vulnerability affects Firefox ESR < 60.8, Firefox     < 68, and Thunderbird < 60.8. (CVE-2019-11729)
