CVE-2015-8393

pcregrep in PCRE before 8.38 mishandles the -q option for binary files, which might allow remote attackers to obtain sensitive information via a crafted file, as demonstrated by a CGI script that sends stdout data to a client.

This update for pcre to version 8.39 (bsc#972127) fixes several issues.

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).

The SUSE Linux Enterprise Server 12 container image has been updated to include security and stability fixes.

The following issues related to building of the container images have been fixed:

• Included krb5 package to avoid the inclusion of krb5-mini which gets selected as a dependency by the Build Service solver. (bsc#1056193)
• Do not install recommended packages when building container images. (bsc#975726)

A number of security issues that have been already fixed by updates released for SUSE Linux Enterprise Server 12 are now included in the base image. A package/CVE cross-reference is available below.
