    12th February, 2018

    firefox regressions


    A security issue affects these releases of Ubuntu and its derivatives:

    • Ubuntu 17.10
    • Ubuntu 16.04 LTS
    • Ubuntu 14.04 LTS
    Summary


    USN-3544-1 caused some regressions in Firefox.

    Software description

    • firefox - Mozilla Open Source web browser
    Details


    USN-3544-1 fixed vulnerabilities in Firefox. The update caused a web
    compatibility regression and a tab crash during printing in some
    circumstances. This update fixes the problem.

    We apologize for the inconvenience.

    Original advisory details:

    Multiple security issues were discovered in Firefox. If a user were
    tricked in to opening a specially crafted website, an attacker could
    potentially exploit these to cause a denial of service via application
    crash, spoof the origin in audio capture prompts, trick the user in to
    providing HTTP credentials for another origin, spoof the addressbar
    contents, or execute arbitrary code. (CVE-2018-5089, CVE-2018-5090,
    CVE-2018-5091, CVE-2018-5092, CVE-2018-5093, CVE-2018-5094, CVE-2018-5095,
    CVE-2018-5097, CVE-2018-5098, CVE-2018-5099, CVE-2018-5100, CVE-2018-5101,
    CVE-2018-5102, CVE-2018-5103, CVE-2018-5104, CVE-2018-5109, CVE-2018-5114,
    CVE-2018-5115, CVE-2018-5117, CVE-2018-5122)

    Multiple security issues were discovered in WebExtensions. If a user were
    tricked in to installing a specially crafted extension, an attacker could
    potentially exploit these to gain additional privileges, bypass
    same-origin restrictions, or execute arbitrary code. (CVE-2018-5105,
    CVE-2018-5113, CVE-2018-5116)

    A security issue was discovered with the developer tools. If a user were
    tricked in to opening a specially crafted website with the developer tools
    open, an attacker could potentially exploit this to obtain sensitive
    information from other origins. (CVE-2018-5106)

    A security issue was discovered with printing. An attacker could
    potentially exploit this to obtain sensitive information from local files.
    (CVE-2018-5107)

    It was discovered that manually entered blob URLs could be accessed by
    subsequent private browsing tabs. If a user were tricked in to entering
    a blob URL, an attacker could potentially exploit this to obtain sensitive
    information from a private browsing context. (CVE-2018-5108)

    It was discovered that dragging certain specially formatted URLs to the
    addressbar could cause the wrong URL to be displayed. If a user were
    tricked in to opening a specially crafted website and dragging a URL to
    the addressbar, an attacker could potentially exploit this to spoof the
    addressbar contents. (CVE-2018-5111)

    It was discovered that WebExtension developer tools panels could open
    non-relative URLs. If a user were tricked in to installing a specially
    crafted extension and running the developer tools, an attacker could
    potentially exploit this to gain additional privileges. (CVE-2018-5112)

    It was discovered that ActivityStream images can attempt to load local
    content through file: URLs. If a user were tricked in to opening a
    specially crafted website, an attacker could potentially exploit this in
    combination with another vulnerability that allowed sandbox protections to
    be bypassed, in order to obtain sensitive information from local files.
    (CVE-2018-5118)

    It was discovered that the reader view will load cross-origin content in
    violation of CORS headers. An attacker could exploit this to bypass CORS
    restrictions. (CVE-2018-5119)
