Package : firefox

Summary

The package firefox before version 61.0-1 is vulnerable to multiple
issues including arbitrary code execution, cross-site request forgery,
same-origin policy bypass, access restriction bypass and information
disclosure.

Resolution

Upgrade to 61.0-1.

pacman -Syu “firefox>=61.0-1”

The problems have been fixed upstream in version 61.0.

Workaround

None.

Description

  • CVE-2018-5186 (arbitrary code execution)

Several memory safety bugs have been found in Firefox before 61.0. Some
of these bugs showed evidence of memory corruption and Mozilla presumes
that with enough effort some of these could be exploited to run
arbitrary code.

  • CVE-2018-5187 (arbitrary code execution)

Several memory safety bugs have been found in Firefox before 61.0. Some
of these bugs showed evidence of memory corruption and Mozilla presumes
that with enough effort some of these could be exploited to run
arbitrary code.

  • CVE-2018-5188 (arbitrary code execution)

Several memory safety bugs have been found in Firefox before 61.0. Some
of these bugs showed evidence of memory corruption and Mozilla presumes
that with enough effort some of these could be exploited to run
arbitrary code.

  • CVE-2018-12356 (arbitrary code execution)

An issue was discovered in password-store.sh in pass in Simple Password
Store 1.7 through 1.7.1. The signature verification routine parses the
output of GnuPG with an incomplete regular expression, which allows
remote attackers to spoof file signatures on configuration files and
extensions scripts. Modifying the configuration file allows the
attacker to inject additional encryption keys under their control,
thereby disclosing passwords to the attacker. Modifying the extension
scripts allows the attacker arbitrary code execution.

  • CVE-2018-12358 (same-origin policy bypass)

Service workers in Firefox before 61.0 can use redirection to avoid the
tainting of cross-origin resources in some instances, allowing a
malicious site to read responses which are supposed to be opaque.

  • CVE-2018-12359 (arbitrary code execution)

A buffer overflow can occur in Firefox before 61.0 when rendering
canvas content while adjusting the height and width of the <canvas>
element dynamically, causing data to be written outside of the
currently computed boundaries. This results in a potentially
exploitable crash.

  • CVE-2018-12360 (arbitrary code execution)

A use-after-free vulnerability can occur in Firefox before 61.0 when
deleting an input element during a mutation event handler triggered by
focusing that element. This results in a potentially exploitable crash.

  • CVE-2018-12361 (arbitrary code execution)

An integer overflow can occur in Firefox before 61.0 in the SwizzleData
code while calculating buffer sizes. The overflowed value is used for
subsequent graphics computations when their inputs are not sanitized
which results in a potentially exploitable crash.

  • CVE-2018-12362 (arbitrary code execution)

An integer overflow can occur in Firefox before 61.0 during graphics
operations done by the Supplemental Streaming SIMD Extensions 3 (SSSE3)
scaler, resulting in a potentially exploitable crash.

  • CVE-2018-12363 (arbitrary code execution)

A use-after-free vulnerability can occur in Firefox before 61.0 when
script uses mutation events to move DOM nodes between documents,
resulting in the old document that held the node being freed but the
node still having a pointer referencing it. This results in a
potentially exploitable crash.

  • CVE-2018-12364 (cross-site request forgery)

A security issue has been found in Firefox before 61.0 where NPAPI
plugins, such as Adobe Flash, can send non-simple cross-origin
requests, bypassing CORS by making a same-origin POST that does a 307
redirect to the target site. This allows for a malicious site to engage
in cross-site request forgery (CSRF) attacks.

  • CVE-2018-12365 (information disclosure)

A security issue has been found in Firefox before 61.0 where a
compromised IPC child process can escape the content sandbox and list
the names of arbitrary files on the file system without user consent or
interaction. This could result in exposure of private local files.

  • CVE-2018-12366 (information disclosure)

An invalid grid size during QCMS (color profile) transformations can
result in the out-of-bounds read interpreted as a float value, in
Firefox before 61.0. This could leak private data into the output.

  • CVE-2018-12367 (information disclosure)

A security issue has been found in Firefox before 61.0. In the previous
mitigations for Spectre, the resolution or precision of various methods
was reduced to counteract the ability to measure precise time
intervals. In that work, PerformanceNavigationTiming was not adjusted
but it was found that it could be used as a precision timer.

  • CVE-2018-12369 (access restriction bypass)

WebExtensions bundled with embedded experiments were not correctly
checked for proper authorization before Firefox 61.0. This allowed a
malicious WebExtension to gain full browser permissions.

  • CVE-2018-12370 (access restriction bypass)

In the Reader View of Firefox before 61.0, SameSite cookie protections
are not checked on exiting. This allows for a payload to be triggered
when Reader View is exited if loaded by a malicious site while Reader
mode is active, bypassing CSRF protections.

  • CVE-2018-12371 (arbitrary code execution)

An integer overflow vulnerability has been found in the Skia library
shipped with Firefox before 61.0, when allocating memory for edge
builders on some systems with at least 16 GB of RAM. This results in
the use of uninitialized memory, resulting in a potentially exploitable
crash.

Impact

A remote attacker can access sensitive information, bypass various
security mechanisms and execute arbitrary code on the affected host.
