Monthly
An issue was discovered in illumos before 2020-10-22, as used in OmniOS before r151030by, r151032ay, and r151034y and SmartOS before 20201022. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Buffer Copy without Size Check vulnerability could allow attackers to overflow a buffer to corrupt adjacent memory.
illumos smbsrv NULL pointer dereference allows system crash. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
illumos osnet-incorporation bcopy() and bzero() implementations make signed instead of unsigned comparisons allowing a system crash. Rated high severity (CVSS 8.6), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
The devzvol_readdir function in illumos does not check the return value of a strchr call, which allows remote attackers to cause a denial of service (NULL pointer dereference and panic) via. Rated medium severity (CVSS 5.0), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as used in Citrix XenServer 6.0.2 and earlier and other products; Oracle Solaris 11 and earlier; illumos before r13724; Joyent. Rated high severity (CVSS 7.2), this vulnerability is low attack complexity. Public exploit code available and EPSS exploitation probability 88.0%.
