Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Mozilla Network Security Services (NSS) before 3.16.2.1, 3.16.x before 3.16.5, and 3.17.x before 3.17.1, as used in Mozilla Firefox before 32.0.3, Mozilla Firefox ESR 24.x before 24.8.1 and 31.x before 31.1.1, Mozilla Thunderbird before 24.8.1 and 31.x before 31.1.2, Mozilla SeaMonkey before 2.29.1, Google Chrome before 37.0.2062.124 on Windows and OS X, and Google Chrome OS before 37.0.2062.120, does not properly parse ASN.1 values in X.509 certificates, which makes it easier for remote attackers to spoof RSA signatures via a crafted certificate, aka a "signature malleability" issue.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Mozilla NSS before 3.16.2.1/3.16.5/3.17.1 improperly parses ASN.1 values in X.509 certificates, enabling attackers to craft certificates with spoofed RSA signatures through signature malleability. This allows remote attackers to impersonate trusted entities by modifying signature values without invalidating the certificate chain.

MitigationUpdate affected Mozilla products (Firefox, Thunderbird, SeaMonkey) and Google Chrome to the specified patched versions or later, which contain the fixed NSS library. For embedded systems using NSS directly, update the NSS library to version 3.16.2.1, 3.16.5, or 3.17.1 or later.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Mozilla Firefox version
    Open Firefox, click menu > Help > About Firefox, or visit about:support, to view the version number
    Affected if Version is 32.0, 32.0.1, 32.0.2, 31.0, 31.1.0, or <= 32.0 (all versions <= 32.0)
  2. Check Mozilla Firefox ESR version
    Open Firefox ESR, click menu > Help > About Firefox ESR, or visit about:support, to view the version number
    Affected if Version is 24.8.0
  3. Check Mozilla Thunderbird version
    Open Thunderbird, click menu > Help > About Thunderbird to view the version number
    Affected if Version is 24.8.0, 31.0, 31.1.0, or 31.1.1, or <= 24.8.0
  4. Check Mozilla SeaMonkey version
    Open SeaMonkey, click menu > Help > About SeaMonkey to view the version number
    Affected if Version matches any listed in the affected range (all versions and <= 2.29 are vulnerable)
  5. Check Google Chrome version
    Open Chrome, click menu > Help > About Google Chrome, or visit chrome://version, to view the version number
    Affected if Version is <= 37.0.2062.120, <= 37.0.2062.103, or matches 37.0.2062.0/3/20/100/102
  6. Check NSS library version directly
    For systems with NSS installed directly, run 'rpm -q nss' (RHEL/CentOS), 'dpkg -l libnss3' (Debian/Ubuntu), or inspect the NSS library file version using 'strings libnss3.so | grep -i "NSS"'
    Affected if NSS version is 3.16.2.0 or earlier, 3.2.x, 3.3.x, 3.4.x, 3.5, or 3.6.x

You are affected if any of your installed products (Firefox, Firefox ESR, Thunderbird, SeaMonkey, Chrome, or NSS library) match the vulnerable versions listed AND you rely on X.509 certificate chain validation, which is enabled by default in these products.
