  - An integer underflow condition exists in the bundled     version of libstagefright in the parseChunk() function     that is triggered when handling 'covr' chunks. An     unauthenticated, remote attacker can exploit this, via     specially crafted media content, to crash the     application or execute arbitrary code. (CVE-2015-7222)

  - A privilege escalation vulnerability exists in the     Extension.jsm script due to a failure to restrict     WebExtension APIs from being injected into documents     without WebExtension principals. An attacker can exploit     this to conduct a cross-site scripting attack, resulting     in the execution of arbitrary script code in a user's     browser session. (CVE-2015-7223)

The version of Firefox installed on the remote Mac OS X host is prior to 43. It is, therefore, affected by the following vulnerabilities :

  - Multiple unspecified memory corruption issues exist due     to improper validation of user-supplied input. A remote     attacker can exploit these issues by convincing a user     to visit a specially crafted web page, resulting in the     execution of arbitrary code. (CVE-2015-7201)

  - Multiple unspecified memory corruption issues exist due     to improper validation of user-supplied input. A remote     attacker can exploit these issues by convincing a user     to visit a specially crafted web page, resulting in the     execution of arbitrary code. (CVE-2015-7202)

  - An overflow condition exists in the LoadFontFamilyData()     function due to improper validation of user-supplied     input. A remote attacker can exploit this to cause a     buffer overflow, resulting in the execution of arbitrary     code. (CVE-2015-7203)

  - A flaw exists in the PropertyWriteNeedsTypeBarrier()     function due to improper handling of unboxed objects     during JavaScript variable assignments. A remote     attacker can exploit this to execute arbitrary code.
    (CVE-2015-7204)

  - A flaw exists in the RtpHeaderParser::Parse() function     due to improper handling of RTP headers. An     unauthenticated, remote attacker can exploit this, via     specially crafted RTP headers, to execute arbitrary     code. (CVE-2015-7205)

  - A same-origin bypass vulnerability exists that is     triggered after a redirect when the function is used     alongside an iframe to host a page. An attacker can     exploit this to gain access to cross-origin URL     information. (CVE-2015-7207)

  - The SetCookieInternal() function improperly allows     control characters (e.g. ASCII code 11) to be inserted     into cookies. An attacker can exploit this to inject     cookies. (CVE-2015-7208)

  - A use-after-free error exists due to improper prevention     of datachannel operations on closed PeerConnections. An     attacker can exploit this to dereference already freed     memory, resulting in the execution of arbitrary code.
    (CVE-2015-7210)

  - A flaw exists in the ParseURI() function due to improper     handling of a hash (#) character in the data: URI. An     attacker can exploit this to spoof the URL bar.
    (CVE-2015-7211)

  - An integer overflow condition exists in the     readMetaData() function due to improper validation of     user-supplied input when handling a specially crafted     MP4 file. An attacker can exploit this to execute     arbitrary code. (CVE-2015-7213)

  - A same-origin bypass vulnerability exists due to     improper handling of 'data:' and 'view-source:' URIs. An     attacker can exploit this to read data from cross-site     URLs and local files. (CVE-2015-7214)

  - An information disclosure vulnerability exists due to     improper handling of error events in web workers. An     attacker can exploit this to gain access to sensitive     cross-origin information. (CVE-2015-7215)

  - Multiple integer underflow conditions exist due to     improper  validation of user-supplied input when     handling HTTP2 frames. An attacker can exploit these to     crash the application, resulting in a denial of service.
    (CVE-2015-7218, CVE-2015-7219)

  - An overflow condition exists in the XDRBuffer::grow()     function due to improper validation of user-supplied     input. An attacker can exploit this to cause a buffer     overflow, resulting in the execution of arbitrary code.
    (CVE-2015-7220)

  - An overflow condition exists in the GrowCapacity()     function due to improper validation of user-supplied     input. An attacker can exploit this to cause a buffer     overflow, resulting in the execution of arbitrary code.
    (CVE-2015-7221)

  - An integer underflow condition exists in the bundled     version of libstagefright in the parseChunk() function     that is triggered when handling 'covr' chunks. An     unauthenticated, remote attacker can exploit this, via     specially crafted media content, to crash the     application or execute arbitrary code. (CVE-2015-7222)

  - A privilege escalation vulnerability exists in the     Extension.jsm script due to a failure to restrict     WebExtension APIs from being injected into documents     without WebExtension principals. An attacker can exploit     this to conduct a cross-site scripting attack, resulting     in the execution of arbitrary script code in a user's     browser session. (CVE-2015-7223)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2833-1 advisory.
