Summary:

USN-3544-1 caused some regressions in Firefox.

Software Description:

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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 17.10:
  firefox                         58.0.2+build1-0ubuntu0.17.10.1

Ubuntu 16.04 LTS:
  firefox                         58.0.2+build1-0ubuntu0.16.04.1

Ubuntu 14.04 LTS:
  firefox                         58.0.2+build1-0ubuntu0.14.04.1

After a standard system update you need to restart Firefox to make
all the necessary changes.
