In LibTomCrypt through 1.18.2 the der_decode_utf8_string function (in der_decode_utf8_string.c) does not properly detect certain invalid UTF-8 sequences. This allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) or read information from other memory locations via carefully crafted DER-encoded data.

NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures encoded within CMS S/MIME PKCS \#7 or PKCS \#12 are likely to be impacted. Applications using NSS for certificate validation or other TLS X.509 OCSP or CRL functionality may be impacted depending on how they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However email clients and PDF viewers that use NSS for signature verification such as Thunderbird LibreOffice Evolution and Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
