7.5 HighFix available

A buffer overflow was discovered in libxml2 20904-GITv2.9.4-16-g0741801. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. The variable len is assigned strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then (i) the content->prefix is appended to buf (if it actually fits) whereupon (ii) content->name is written to the buffer. However, the check for whether the content->name actually fits also uses 'len' rather than the updated buffer length strlen(buf). This allows us to write about "size" many bytes beyond the allocated memory. This vulnerability causes programs that use libxml2, such as PHP, to crash.

Updated libxml2 & perl-XML-LibXML packages fix security vulnerabilities

Use-after-free error could lead to crash (CVE-2016-4658).

Use-after-free vulnerability in libxml2 through 2.9.4 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function (CVE-2016-5131).

libxml2 2.9.4 and earlier does not offer a flag directly indicating that the current document may be read but other files may not be opened, which makes it easier for remote attackers to conduct XML External Entity (XXE) attacks via a crafted document (CVE-2016-9318).

Heap buffer overflow in xmlAddID (CVE-2017-0663).

Integer overflow in memory debug code in libxml2 before 2.9.5 (CVE-2017-5130).

NULL pointer deref in xmlDumpElementContent (CVE-2017-5969).

Prevent unwanted external entity reference (CVE-2017-7375).

Increase buffer space for port in HTTP redirect support (CVE-2017-7376).

The function xmlSnprintfElementContent in valid.c was vulnerable to a stack buffer overflow (CVE-2017-9047, CVE-2017-9048).

The function xmlDictComputeFastKey in dict.c was vulnerable to a heap-based buffer over-read (CVE-2017-9049).

The function xmlDictAddString was vulnerable to a heap-based buffer over-read (CVE-2017-9050).

It was discovered that libxml2 incorrecty handled certain files. An attacker could use this issue with specially constructed XML data to cause libxml2 to consume resources, leading to a denial of service (CVE-2017-15412).

Wei Lei discovered that libxml2 incorrecty handled certain parameter entities. An attacker could use this issue with specially constructed XML data to cause libxml2 to consume resources, leading to a denial of service (CVE-2017-16932).

The libxml2 package has been updated to version 2.9.7 to fix these issues and several other bugs.

Security update for SLES 12 Docker image

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.
