openSUSE Security Update : python-cryptography (openSUSE-2018-1281)
Medium Nessus Plugin ID 118451
SynopsisThe remote openSUSE host is missing a security update.
DescriptionThis update for python-cryptography fixes the following issues :
- CVE-2018-10903: The finalize_with_tag API did not enforce a minimum tag length. If a user did not validate the input length prior to passing it to finalize_with_tag an attacker could craft an invalid payload with a shortened tag (e.g. 1 byte) such that they would have a 1 in 256 chance of passing the MAC check. GCM tag forgeries could have caused key leakage (bsc#1101820).
This update was imported from the SUSE:SLE-15:Update update project.
SolutionUpdate the affected python-cryptography packages.
