[USN-5168-1] NSS vulnerability

Severity High
Affected Packages 12
CVEs 1
Info Packages Vulnerabilities

NSS could be made to crash or run programs if it verified a specially crafted signature.

Tavis Ormandy discovered that NSS incorrectly handled verifying DSA/RSA-PSS
signatures. A remote attacker could use this issue to cause NSS to crash,
resulting in a denial of service, or possibly execute arbitrary code.
