| CVE-2017-7546 | 2 Debian, Postgresql | 2 Debian Linux, Postgresql | 2019-10-09 | 7.5 HIGH | 9.8 CRITICAL |
| PostgreSQL versions before 9.2.22, 9.3.18, 9.4.13, 9.5.8 and 9.6.4 are vulnerable to incorrect authentication flaw allowing remote attackers to gain access to database accounts with an empty password. | |||||
| CVE-2017-12172 | 1 Postgresql | 1 Postgresql | 2019-10-09 | 7.2 HIGH | 6.7 MEDIUM |
| PostgreSQL 10.x before 10.1, 9.6.x before 9.6.6, 9.5.x before 9.5.10, 9.4.x before 9.4.15, 9.3.x before 9.3.20, and 9.2.x before 9.2.24 runs under a non-root operating system account, and database superusers have effective ability to run arbitrary code under that system account. PostgreSQL provides a script for starting the database server during system boot. Packages of PostgreSQL for many operating systems provide their own, packager-authored startup implementations. Several implementations use a log file name that the database superuser can replace with a symbolic link. As root, they open(), chmod() and/or chown() this log file name. This often suffices for the database superuser to escalate to root privileges when root starts the server. | |||||
| CVE-2007-4772 | 4 Canonical, Debian, Postgresql and 1 more | 4 Ubuntu Linux, Debian Linux, Postgresql and 1 more | 2019-10-09 | 4.0 MEDIUM | N/A |

| PostgreSQL versions before 9.2.22, 9.3.18, 9.4.13, 9.5.8 and 9.6.4 are vulnerable to authorization flaw allowing remote authenticated attackers to retrieve passwords from the user mappings defined by the foreign server owners without actually having the privileges to do so. | |||||
| CVE-2017-7548 | 1 Postgresql | 1 Postgresql | 2019-10-03 | 4.0 MEDIUM | 7.5 HIGH |
| PostgreSQL versions before 9.4.13, 9.5.8 and 9.6.4 are vulnerable to authorization flaw allowing remote authenticated attackers with no privileges on a large object to overwrite the entire contents of the object, resulting in a denial of service. | |||||

| PostgreSQL 8.0.x before 8.0.6 and 8.1.x before 8.1.2, when running on Windows, allows remote attackers to cause a denial of service (postmaster exit and no new connections) via a large number of simultaneous connection requests. | |||||
| CVE-2005-1410 | 2 Postgresql, Trustix | 2 Postgresql, Secure Linux | 2018-10-19 | 2.1 LOW | N/A |
| The tsearch2 module in PostgreSQL 7.4 through 8.0.x declares the (1) dex_init, (2) snb_en_init, (3) snb_ru_init, (4) spell_init, and (5) syn_init functions as "internal" even when they do not take an internal argument, which allows attackers to cause a denial of service (application crash) and possibly have other impacts via SQL commands that call other functions that accept internal arguments. | |||||
| CVE-2005-1409 | 1 Postgresql | 1 Postgresql | 2018-10-19 | 7.5 HIGH | N/A |
| PostgreSQL 7.3.x through 8.0.x gives public EXECUTE access to certain character conversion functions, which allows unprivileged users to call those functions with malicious values, with unknown impact, aka the "Character conversion vulnerability." | |||||
| CVE-2006-2314 | 1 Postgresql | 1 Postgresql | 2018-10-18 | 7.5 HIGH | N/A |
| PostgreSQL 8.1.x before 8.1.4, 8.0.x before 8.0.8, 7.4.x before 7.4.13, 7.3.x before 7.3.15, and earlier versions allows context-dependent attackers to bypass SQL injection protection methods in applications that use multibyte encodings that allow the "\" (backslash) byte 0x5c to be the trailing byte of a multibyte character, such as SJIS, BIG5, GBK, GB18030, and UHC, which cannot be handled correctly by a client that does not understand multibyte encodings, aka a second variant of "Encoding-Based SQL Injection." NOTE: it could be argued that this is a class of issue related to interaction errors between the client and PostgreSQL, but a CVE has been assigned since PostgreSQL is treating this as a preventative measure against this class of problem. | |||||
| CVE-2006-2313 | 1 Postgresql | 1 Postgresql | 2018-10-18 | 7.5 HIGH | N/A |
| PostgreSQL 8.1.x before 8.1.4, 8.0.x before 8.0.8, 7.4.x before 7.4.13, 7.3.x before 7.3.15, and earlier versions allows context-dependent attackers to bypass SQL injection protection methods in applications via invalid encodings of multibyte characters, aka one variant of "Encoding-Based SQL Injection." | |||||
| CVE-2007-3280 | 1 Postgresql | 1 Postgresql | 2018-10-16 | 9.0 HIGH | N/A |
| The Database Link library (dblink) in PostgreSQL 8.1 implements functions via CREATE statements that map to arbitrary libraries based on the C programming language, which allows remote authenticated superusers to map and execute a function from any library, as demonstrated by using the system function in libc.so.6 to gain shell access. | |||||
| CVE-2007-3279 | 1 Postgresql | 1 Postgresql | 2018-10-16 | 10.0 HIGH | N/A |

| The query planner in PostgreSQL before 8.0.11, 8.1 before 8.1.7, and 8.2 before 8.2.2 does not verify that a table is compatible with a "previously made query plan," which allows remote authenticated users to cause a denial of service (server crash) and possibly access database content via an "ALTER COLUMN TYPE" SQL statement, which can be leveraged to read arbitrary memory from the server. | |||||
| CVE-2007-6601 | 1 Postgresql | 1 Postgresql | 2018-10-15 | 7.2 HIGH | N/A |
| The DBLink module in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, 7.4 before 7.4.19, and 7.3 before 7.3.21, when local trust or ident authentication is used, allows remote attackers to gain privileges via unspecified vectors.
