PARTIAL Summary
rsyslog before 7.6.6 and 8.x before 8.4.1 and sysklogd 1.5 and earlier allows remote attackers to cause a denial of service (crash), possibly execute arbitrary code, or have other unspecified impact via a crafted priority (PRI) value that triggers an out-of-bounds array access.
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.

A flaw was found in the way rsyslog handled invalid log message priority values. In certain configurations, a local attacker, or a remote attacker able to connect to the rsyslog port, could use this flaw to crash the rsyslog daemon or, potentially, execute arbitrary code as the user running the rsyslog daemon.

(CVE-2014-3634) Red Hat would like to thank Rainer Gerhards of rsyslog upstream for reporting this issue. All rsyslog5 and rsyslog users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, the rsyslog service will be restarted automatically. last seen 2020-06-01 modified 2020-06-02 plugin id 78595 published 2014-10-21 reporter This script is Copyright (C) 2014-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/78595 title RHEL 5 / 6 : rsyslog5 and rsyslog (RHSA-2014:1671) NASL family Scientific Linux Local Security Checks NASL id SL_20141013_RSYSLOG_ON_SL7_X.NASL description A flaw was found in the way rsyslog handled invalid log message priority values.
