Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10 - Ubuntu 12.10 - Ubuntu 12.04 LTS

Summary:

libyaml-libyaml-perl could be made to crash or run programs if it opened a specially crafted YAML file.

Software Description: - libyaml-libyaml-perl: Perl interface to libyaml, a YAML implementation

Details:

Florian Weimer discovered that libyaml-libyaml-perl incorrectly handled certain large YAML documents. An attacker could use this issue to cause libyaml-libyaml-perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2013-6393)

Ivan Fratric discovered that libyaml-libyaml-perl incorrectly handled certain malformed YAML documents. An attacker could use this issue to cause libyaml-libyaml-perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2014-2525)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 13.10:
libyaml-libyaml-perl 0.38-3ubuntu0.13.10.1

Ubuntu 12.10:
libyaml-libyaml-perl 0.38-3ubuntu0.12.10.1

Ubuntu 12.04 LTS:
libyaml-libyaml-perl 0.38-2ubuntu0.1

After a standard system update you need to restart applications using libyaml-libyaml-perl to make all the necessary changes.

Title: DSA-2850-1 libyaml - heap-based buffer overflow
Description: Florian Weimer of the Red Hat Product Security Team discovered a heap-based buffer overflow flaw in LibYAML, a fast YAML 1.1 parser and emitter library. A remote attacker could provide a YAML document with a specially-crafted tag that, when parsed by an application using libyaml, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.

Description: erl-YAML-LibYAML was updated to fix three security issues. These security issues were fixed: - CVE-2013-6393: The yaml_parser_scan_tag_uri function in scanner.c in LibYAML before 0.1.5 performed an incorrect cast, which allowed remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted tags in a YAML document, which triggered a heap-based buffer overflow (bnc#860617, bnc#911782).
