Multiple security issues have been found in Thunderbird: Multiple vulnerabilities may lead to the execution of arbitrary code or denial of service.

The remote NewStart CGSL host, running version MAIN 4.06, has firefox packages installed that are affected by multiple vulnerabilities:

  - Lack of correct bounds checking in Skia in Google Chrome     prior to 73.0.3683.75 allowed a remote attacker to     perform an out of bounds memory read via a crafted HTML     page. (CVE-2019-5798)

  - Cross-origin images can be read from a canvas element in     violation of the same-origin policy using the     transferFromImageBitmap method. *Note: This only affects     Firefox 65. Previous versions are unaffected.*. This     vulnerability affects Firefox < 65.0.1. (CVE-2018-18511)

  - Cross-origin images can be read in violation of the     same-origin policy by exporting an image after using     createImageBitmap to read the image and then rendering     the resulting bitmap image within a canvas element. This     vulnerability affects Firefox < 66. (CVE-2019-9797)

  - Insufficient vetting of parameters passed with the     Prompt:Open IPC message between child and parent     processes can result in the non-sandboxed parent process     opening web content chosen by a compromised child     process. When combined with additional vulnerabilities     this could result in executing arbitrary code on the     user's computer. This vulnerability affects Firefox ESR     < 60.7.2, Firefox < 67.0.4, and Thunderbird < 60.7.2.
    (CVE-2019-11708)

  - A type confusion vulnerability can occur when     manipulating JavaScript objects due to issues in     Array.pop. This can allow for an exploitable crash. We     are aware of targeted attacks in the wild abusing this     flaw. This vulnerability affects Firefox ESR < 60.7.1,     Firefox < 67.0.3, and Thunderbird < 60.7.2.
    (CVE-2019-11707)

  - png_image_free in png.c in libpng 1.6.x before 1.6.37     has a use-after-free because png_image_free_function is     called under png_safe_execute. (CVE-2019-7317)

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

The remote NewStart CGSL host, running version MAIN 4.06, has thunderbird packages installed that are affected by multiple vulnerabilities:

  - Lack of correct bounds checking in Skia in Google Chrome     prior to 73.0.3683.75 allowed a remote attacker to     perform an out of bounds memory read via a crafted HTML     page. (CVE-2019-5798)

  - A flaw in Thunderbird's implementation of iCal causes a     stack buffer overflow in icalrecur_add_bydayrules when     processing certain email messages, resulting in a     potentially exploitable crash. This vulnerability     affects Thunderbird < 60.7.1. (CVE-2019-11705)

  - A flaw in Thunderbird's implementation of iCal causes a     type confusion in icaltimezone_get_vtimezone_properties     when processing certain email messages, resulting in a     crash. This vulnerability affects Thunderbird < 60.7.1.
    (CVE-2019-11706)
