HIGH Summary
The compile_branch function in pcre_compile.c in PCRE 8.x before 8.39 and pcre2_compile.c in PCRE2 before 10.22 mishandles patterns containing an (*ACCEPT) substring in conjunction with nested parentheses, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror, aka ZDI-CAN-3542.

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.

If you use pcre extensively please be aware that this is an update to a new version. Please make sure that your software works with the updated version. This version fixes a number of vulnerabilities that affect pcre and applications using the libary when accepting untrusted input as regular expressions or as part thereof. Remote attackers could have caused the application to crash, disclose information or potentially execute arbitrary code. These security issues were fixed : - CVE-2014-8964: Heap-based buffer overflow in PCRE allowed remote attackers to cause a denial of service (crash) or have other unspecified impact via a crafted regular expression, related to an assertion that allows zero repeats (bsc#906574). - CVE-2015-2325: Heap buffer overflow in compile_branch() (bsc#924960). - CVE-2015-3210: Heap buffer overflow in pcre_compile2() / compile_regex() (bsc#933288) - CVE-2015-3217: PCRE Library Call Stack Overflow Vulnerability in match() (bsc#933878). - CVE-2015-5073: Library Heap Overflow Vulnerability in find_fixedlength() (bsc#936227). - bsc#942865: heap overflow in compile_regex() - CVE-2015-8380: The pcre_exec function in pcre_exec.c mishandled a // pattern with a \01 string, which allowed remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror (bsc#957566). - CVE-2015-2327: PCRE mishandled certain patterns with internal recursive back references, which allowed remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror (bsc#957567). - bsc#957598: Various security issues - CVE-2015-8381: Heap Overflow in compile_regex() (bsc#957598). - CVE-2015-8382: Regular Expression Uninitialized Pointer Information Disclosure Vulnerability (ZDI-CAN-2547)(bsc#957598). - CVE-2015-8383: Buffer overflow caused by repeated conditional group(bsc#957598). - CVE-2015-8384: Buffer overflow caused by recursive back reference by name within certain group(bsc#957598). - CVE-2015-8385: Buffer overflow caused by forward reference by name to certain group(bsc#957598). - CVE-2015-8386: Buffer overflow caused by lookbehind assertion(bsc#957598). - CVE-2015-8387: Integer overflow in subroutine calls(bsc#957598). - CVE-2015-8388: Buffer overflow caused by certain patterns with an unmatched closing parenthesis(bsc#957598). - CVE-2015-8389: Infinite recursion in JIT compiler when processing certain patterns(bsc#957598). - CVE-2015-8390: Reading from uninitialized memory when processing certain patterns(bsc#957598). - CVE-2015-8391: Some pathological patterns causes pcre_compile() to run for a very long time(bsc#957598). - CVE-2015-8392: Buffer overflow caused by certain patterns with duplicated named groups(bsc#957598). - CVE-2015-8393: Information leak when running pcgrep -q on crafted binary(bsc#957598). - CVE-2015-8394: Integer overflow caused by missing check for certain conditions(bsc#957598). - CVE-2015-8395: Buffer overflow caused by certain references(bsc#957598). - CVE-2015-2328: PCRE mishandled the /((?(R)a|(?1)))+/ pattern and related patterns with certain recursion, which allowed remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted regular expression (bsc#957600). - CVE-2016-1283: The pcre_compile2 function in pcre_compile.c in PCRE mishandled certain patterns with named subgroups, which allowed remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression (bsc#960837). - CVE-2016-3191: The compile_branch function in pcre_compile.c in pcre2_compile.c mishandled patterns containing an (*ACCEPT) substring in conjunction with nested parentheses, which allowed remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted regular expression (bsc#971741). These non-security issues were fixed : - JIT compiler improvements - performance improvements - The Unicode data tables have been updated to Unicode 7.0.0.
