LOW Privileges required
NONE Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
PCRE before 8.38 mishandles the interaction of lookbehind assertions and mutually recursive subpatterns, which allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.

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 Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2016-1025.NASL description From Red Hat Security Advisory 2016:1025 : An update for pcre is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. PCRE is a Perl-compatible regular expression library. Security Fix(es) : * Multiple flaws were found in the way PCRE handled malformed regular expressions. An attacker able to make an application using PCRE process a specially crafted regular expression could use these flaws to cause the application to crash or, possibly, execute arbitrary code.

A remote attacker can exploit this to bypass restrictions. - A flaw exists in file ext/standard/streamsfuncs.c in the stream_get_meta_data() function due to a failure to restrict writing user-supplied data to fields not already set. A remote attacker can exploit this to falsify the output of the function, resulting in the insertion of malicious metadata. - A type confusion error exists in file ext/wddx/wddx.c in the php_wddx_pop_element() function when deserializing WDDX packets. A remote attacker can exploit this to have an unspecified impact. - A flaw exists in file ext/phar/phar_object.c in the PharFileInfo::getContent() method due to the use of uninitialized memory causing improper validation of user-supplied input. A remote attacker can exploit this to corrupt memory, resulting in a denial of service or the execution of arbitrary code. - A NULL pointer dereference flaw exists in file ext/phar/tar.c in the phar_tar_setupmetadata() function when parsing metadata from a crafted TAR file. A remote attacker can exploit this to cause a denial of service. - An integer overflow condition exists in file ext/standard/iptc.c in the iptcembed() function due to improper validation of user-supplied input. A remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service or the execution of arbitrary code. - An overflow condition exists in file ext/phar/tar.c in the phar_parse_tarfile() function due to improper validation of user-supplied input when decompressing TAR files. A remote attacker can exploit this to cause a stack-based buffer overflow, resulting in a denial of service or the execution of arbitrary code.
