PARTIAL Summary
The snprintf implementation in PostgreSQL before 9.0.20, 9.1.x before 9.1.16, 9.2.x before 9.2.11, 9.3.x before 9.3.7, and 9.4.x before 9.4.2 does not properly handle system-call errors, which allows attackers to obtain sensitive information or have other unspecified impact via unknown vectors, as demonstrated by an out-of-memory error.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family Debian Local Security Checks NASL id DEBIAN_DLA-227.NASL description Several vulnerabilities were discovered in PostgreSQL, a relational database server system. The 8.4 branch is EOLed upstream, but still present in Debian squeeze. This new LTS minor version contains the fixes that were applied upstream to the 9.0.20 version, backported to 8.4.22 which was the last version officially released by the PostgreSQL developers. This LTS effort for squeeze-lts is a community project sponsored by credativ GmbH. CVE-2015-3165: Remote crash SSL clients disconnecting just before the authentication timeout expires can cause the server to crash. CVE-2015-3166: Information exposure The 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. CVE-2015-3167: Possible side-channel key exposure In contrib/pgcrypto, some cases of decryption with an incorrect key could report other error message texts. Fix by using a one-size-fits-all message. Note that the next round of minor releases for PostgreSQL have already been scheduled for early June 2015. There will be a corresponding 8.4.22lts3 update at the same time.

A remote attacker, by sending crafted XML data, can exploit this to disclose arbitrary files. (CVE-2014-3600) - An authentication bypass vulnerability exists in the Apache ActiveMQ component due to a flaw in the LDAPLoginModule implementation. A remote attacker can exploit this to bypass authentication mechanisms. (CVE-2014-3612) - Multiple cross-site scripting vulnerabilities exist in the administrative console of Apache ActiveMQ that allow a remote attacker to inject arbitrary HTML or web scripts. (CVE-2014-8110) - An invalid free memory error exists due to improper validation of user-supplied input when a DTLS peer receives application data between ChangeCipherSpec and Finished messages. A remote attacker can exploit this to corrupt memory, resulting in a denial of service or the execution of arbitrary code. (CVE-2014-8176) - A denial of service vulnerability exists when processing an ECParameters structure due to an infinite loop that occurs when a specified curve is over a malformed binary polynomial field. A remote attacker can exploit this to perform a denial of service against any system that processes public keys, certificate requests, or certificates. This includes TLS clients and TLS servers with client authentication enabled. (CVE-2015-1788) - A denial of service vulnerability exists due to improper validation of the content and length of the ASN1_TIME string by the X509_cmp_time() function. A remote attacker can exploit this, via a malformed certificate and CRLs of various sizes, to cause a segmentation fault, resulting in a denial of service condition. TLS clients that verify CRLs are affected. TLS clients and servers with client authentication enabled may be affected if they use custom verification callbacks.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. PostgreSQL is an advanced object-relational database management system (DBMS). A double-free flaw was found in the connection handling. An unauthenticated attacker could exploit this flaw to crash the PostgreSQL back end by disconnecting at approximately the same time as the authentication time out is triggered. (CVE-2015-3165) It was discovered that PostgreSQL did not properly check the return values of certain standard library functions. If the system is in a state that would cause the standard library functions to fail, for example memory exhaustion, an authenticated user could exploit this flaw to disclose partial memory contents or cause the GSSAPI authentication to use an incorrect keytab file. (CVE-2015-3166) It was discovered that the pgcrypto module could return different error messages when decrypting certain data with an incorrect key. This can help an authenticated user to launch a possible cryptographic attack, although no suitable attack is currently known.
