* New upstream security/bug fix release (LP: #1457093) - Avoid possible crash when client disconnects just before the authentication timeout expires. If the timeout interrupt fired partway through the session shutdown sequence, SSL-related state would be freed twice, typically causing a crash and hence denial of service to other sessions. Experimentation shows that an unauthenticated remote attacker could trigger the bug somewhat consistently, hence treat as security issue. (CVE-2015-3165) - Improve detection of system-call failures Our replacement implementation of snprintf() failed to check for errors reported by the underlying system library calls; the main case that might be missed is out-of-memory situations. In the worst case this might lead to information exposure, due to our code assuming that a buffer had been overwritten when it hadn't been. Also, there were a few places in which security-relevant calls of other system library functions did not check for failure. It remains possible that some calls of the *printf() family of functions are vulnerable to information disclosure if an out-of-memory error occurs at just the wrong time. We judge the risk to not be large, but will continue analysis in this area. (CVE-2015-3166) - In contrib/pgcrypto, uniformly report decryption failures as Wrong key or corrupt data Previously, some cases of decryption with an incorrect key could report other error message texts. It has been shown that such variance in error reports can aid attackers in recovering keys from other systems. While it's unknown whether pgcrypto's specific behaviors are likewise exploitable, it seems better to avoid the risk by using a one-size-fits-all message. (CVE-2015-3167) - Protect against wraparound of multixact member IDs Under certain usage patterns, the existing defenses against this might be insufficient, allowing pg_multixact/members files to be removed too early, resulting in data loss. The fix for this includes modifying the server to fail transactions that would result in overwriting old multixact member ID data, and improving autovacuum to ensure it will act proactively to prevent multixact member ID wraparound, as it does for transaction ID wraparound. - See release notes for details about other fixes. -- Martin Pitt <martin.p...@ubuntu.com> Wed, 20 May 2015 23:08:58 +0200 ** Changed in: postgresql-9.3 (Ubuntu Trusty) Status: In Progress => Fix Released ** Changed in: postgresql-9.4 (Ubuntu Utopic) Status: In Progress => Fix Released -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to postgresql-9.1 in Ubuntu. https://bugs.launchpad.net/bugs/1457093 Title: New upstream microreleases 9.1.16, 9.3.7, 9.4.2 Status in postgresql-9.1 package in Ubuntu: Invalid Status in postgresql-9.3 package in Ubuntu: Invalid Status in postgresql-9.4 package in Ubuntu: Fix Committed Status in postgresql-9.1 source package in Precise: Fix Released Status in postgresql-9.1 source package in Trusty: Fix Released Status in postgresql-9.3 source package in Trusty: Fix Released Status in postgresql-9.4 source package in Utopic: Fix Released Status in postgresql-9.4 source package in Vivid: Fix Released Status in postgresql-9.4 source package in Wily: Fix Committed Bug description: PostgreSQL will push out new microreleases on Friday, 2015-05-22.
