The default is hashes that draw perpendicularly to geometry, but any angle is possible.

Hash-Line symbols made from repeating line symbol segments.

These symbols can be drawn offset from the geometry and can include line decorations like marker symbols along the line and/or at the line endpoints.

Cartographic-Line symbols with properties to control repetitive dash patterns, line joins, and line caps.

Simple-Simple, fast-drawing solid lines or one-pixel-wide lines with a predefined pattern.

For example, a marker line can be combined with a simple line to draw a solid line with a repeating pattern of markers along it. Any number of layers of any line symbol type can be combined in a single line symbol. As graphics, lines can be used as borders, leaders for arrows and other annotation, and freehand drawing. Lines are also used to outline other features such as polygons, points, and labels. Line symbols are used to draw linear data such as transportation networks, water systems, boundaries, zonings, and other connective networks.

Improving line symbol drawing performance.

This would only be a security issue if the hostname is validated before with a different parser. The Uri class implicitly lowercases the hostname when the class is initialized. Regex.IsMatch("hac\u212A", "HACK", RegexOptions.IgnoreCase) = true values extracted from regex group will not be converted implicitly. A developer should not assume that ASCII characters are the only ones to match. Input.Normalize(NormalizationForm.FormKC)Īside from the obvious functions, regex evaluation with the IgnoreCase option supports Unicode transformations.

For example, this python code snippet illustrates a second operation where the non-ascii characters are truncated during string decoding. This has limited risk, but it is possible that output value gets transformed later to only keep the ASCII ones. It is, however, supported in APIs such as string.Equals(input1,input2, StringComparison.CurrentCultureIgnoreCase).įinally, some Unicode character will result into multiple characters where only part of those are ASCII. ** The third observation is that German B in C# may not be transformed with the toUpper() function. But in terms of security, this further reduces the size of the already limited character set available to perform these attacks. In terms of internationalization, it represents an incomplete case mapping implementation. The second highlight is that both C# and Go only support two characters for uppercasing. This is likely to introduce unexpected behaviors because the original code might not have been built with Unicode support in mind. PHP used to provide aliasing (overloading) for the multibyte version of those functions. When a PHP developer is introducing Unicode lowercasing, it is done willingly using the multibyte function mb_strtolower. The first is that PHP does not have potential side effects when applying strtolower() or strtoupper(), it will only transform ASCII characters. There are four main observations to extract from the previous grid.

This way even the reset form is only sent to the original email entered by the user.

This code was fixed by using the email already stored in the database. Search for an email - Case _insensitive_ Special Unicode characters have the chance to be converted to punycode when sent to the SMTP service. A special Unicode character can be used to trigger a collision. The issue is that the search is case insensitive.

In this password reset form from Django, an email value is received, the user information is fetched and an email is sent to each user that were matched. An example of a logic flaw is the one that affected Django and Github: password reset based on email submission. Conditions that cannot be crossed become so, thanks to permissive Unicode comparisons. How does vulnerable code look like? Security bugs revolve around logic flaws.
