Josh Kupershmidt discovered the pgCrypto extension could expose several bytes of server memory if the crypt() function was provided a too-short salt. An attacker could use this flaw to read private data.
(CVE-2015-5288)
Oskari Saarenmaa discovered that the json and jsonb handlers could exhaust available stack space. An attacker could use this flaw to perform a denial of service attack. This issue only affected Ubuntu 14.04 LTS and Ubuntu 15.04. (CVE-2015-5289).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
