Mozilla Firefox was updated to 68.3esr (MFSA 2019-37 bsc#1158328)

CVE-2019-17011: Fixed a use-after-free when retrieving a document in antitracking (bmo#1591334)

CVE-2019-17012: Fixed multiple memmory issues (bmo#1449736, bmo#1533957, bmo#1560667,bmo#1567209, bmo#1580288, bmo#1585760, bmo#1592502)

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

The version of Firefox ESR installed on the remote Windows host is prior to 68.3. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-37 advisory, including the following:

  - 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. (CVE-2019-11745)

  - When using nested workers, a use-after-free could occur during worker destruction. This resulted in a     potentially exploitable crash. (CVE-2019-17008)

  - Mozilla developers Christoph Diehl, Nathan Froyd, Jason Kratzer, Christian Holler, Karl Tomlinson, Tyson     Smith 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. (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 version of Firefox installed on the remote Windows host is prior to 71.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-36 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. (CVE-2019-11745)

  - Improper refcounting of soft token session objects could     cause a use-after-free and crash (likely limited to a denial     of service). (CVE-2019-11756)

  - When setting a thread name on Windows in WebRTC, an     incorrect number of arguments could have been supplied,     leading to stack corruption and a potentially exploitable     crash.
    Note: this issue only occurs on Windows. Other operating     systems are unaffected. (CVE-2019-13722)

  - When using nested workers, a use-after-free could occur     during worker destruction. This resulted in a potentially     exploitable crash. (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.
    (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. (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. (CVE-2019-17011)

  - Mozilla developers Christoph Diehl, Nathan Froyd, Jason     Kratzer, Christian Holler, Karl Tomlinson, Tyson Smith     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.
    (CVE-2019-17012)

  - Mozilla developers and community members Philipp, Diego     Calleja, Mikhail Gavrilov, Jason Kratzer, Christian     Holler, Markus Stange, Tyson Smith reported memory safety     bugs present in Firefox 70. 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. (CVE-2019-17013)

  - If an image had not loaded correctly (such as when it is     not actually an image), it could be dragged and dropped     cross-domain, resulting in a cross-origin information leak.
    (CVE-2019-17014)     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 Thunderbird installed on the remote Windows host is prior to 68.3. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-38 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

New mozilla-firefox packages are available for Slackware 14.2 and
-current to fix security issues.

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)
