CVE-2015-5522 HTML Tidy vulnerabilities
Title: HTML Tidy vulnerabilities
Summary: HTML Tidy could be made to crash or run programs if it processed specially
crafted data.
Fernando Muñoz discovered that HTML Tidy incorrectly handled memory. If a
user or automated system were tricked into processing specially crafted
data, applications linked against HTML Tidy could be made to crash, leading
to a denial of service, or possibly execute arbitrary code.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2015-5523 [MEDIUM] CWE-122 tidy: heap buffer overflow in ParseValue()
tidy: heap buffer overflow in ParseValue()
The ParseValue function in lexer.c in tidy before 4.9.31 allows remote attackers to cause a denial of service (crash) via vectors involving multiple whitespace characters before an empty href, which triggers a large memory allocation.
It was discovered that tidy did not properly process certain character sequences. By tricking an application that is using tidy into processing a specially crafted HTML document, a remote attacker could exploit this flaw to cause a crash or, possibly, execute arbitrary code with the privileges of the affected application.
