CVE-2013-1741
Runaway memset in certificate parsing on 64-bit computers leading to a crash by attempting to write 4Gb of nulls.
CVE-2013-5606
Certificate validation with the verifylog mode did not return validation errors, but instead expected applications to determine the status by looking at the log.
CVE-2014-1491
Ticket handling protection mechanisms bypass due to the lack of restriction of public values in Diffie-Hellman key exchanges.
CVE-2014-1492
Incorrect IDNA domain name matching for wildcard certificates could allow specially crafted invalid certificates to be considered as valid.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
