Notes
sbeattie
upstream fixed this for xsltproc, but libxslt remains unfixed not clear what the security impact of this is
mdeslaur
as of 2022-08-05, no indication that upstream will fix this
ccdm94
there is no upstream patch provided for this issue. The random function in libxslt does not guarantee it will adhere to all cryptographic requirements, and applications using libxslt are expected to be the ones performing the seeding of the system's PRNG in order to achieve proper randomness. For this reason, status for all releases will be set to ignored.
