Software Description: - pcre3: Perl 5 Compatible Regular Expression Library

Details:

Michele Spagnuolo discovered that PCRE incorrectly handled certain regular expressions. A remote attacker could use this issue to cause applications using PCRE to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS. (CVE-2014-8964)

Kai Lu discovered that PCRE incorrectly handled certain regular expressions. A remote attacker could use this issue to cause applications using PCRE to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS and Ubuntu 15.04. (CVE-2015-2325, CVE-2015-2326)

Wen Guanxing discovered that PCRE incorrectly handled certain regular expressions. A remote attacker could use this issue to cause applications using PCRE to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 15.04. (CVE-2015-3210)
