SUSE CVE-2023-53487

In the Linux kernel, the following vulnerability has been resolved: powerpc/rtasflash: allow user copy to flash block cache objects With hardened usercopy enabled CONFIGHARDENEDUSERCOPY=y, using the /proc/powerpc/rtas/firmwareupdate interface to prepare a system firmware update yields a BUG: kern...

Varnish varnish-modules before 0.17.1 allows remote attackers to cause a denial of service (daemon restart) in some configurations. This does not affect organizations that only install the Varnish Cache product; however, it is common to install both Varnish Cache and varnish-modules. Specifically, an assertion failure or NULL pointer dereference can be triggered in Varnish Cache through the varnish-modules header.append() and header.copy() functions. For some Varnish Configuration Language (VCL) files, this gives remote clients an opportunity to cause a Varnish Cache restart. A restart reduces overall availability and performance due to an increased number of cache misses, and may cause higher load on backend servers.
