• [SECURITY] [DSA 5492-1] linux security update (2/2)

    From Salvatore Bonaccorso@1:229/2 to All on Sat Sep 9 23:50:01 2023
    [continued from previous message]

    Oleksii Oleksenko discovered that on some AMD CPUs with the Zen1
    micro architecture an integer division by zero may leave stale
    quotient data from a previous division, resulting in a potential
    leak of sensitive data.

    CVE-2023-34319

    Ross Lagerwall discovered a buffer overrun in Xen's netback driver
    which may allow a Xen guest to cause denial of service to the
    virtualisation host my sending malformed packets.

    CVE-2023-40283

    A use-after-free was discovered in Bluetooth L2CAP socket handling.

    For the stable distribution (bookworm), these problems have been fixed in version 6.1.52-1. This update is released without armel builds. Changes
    in the new stable series import cause a substantial increase of the
    compressed image for marvell flavour. This issue will be addressed in a
    future linux update.

    We recommend that you upgrade your linux packages.
