Description

In libxslt 1.1.29 and earlier, the EXSLT math.random function was not initialized with a random seed during startup, which could cause usage of this function to produce predictable outputs.

Statement

The xslt random function provided by libxslt does not offer any security or cryptography guarantees. Applications using libxslt that rely on non-repeatable randomness should be seeding the system PRNG (srand()) themselves, as they would if calling rand() directly.
