In ovs versions v0.90.0 through v2.5.0 are vulnerable to heap buffer over-read in flow.c. An unsafe comparison of “minimasks” function could lead access to an unmapped region of memory. This vulnerability is capable of crashing the software, memory modification, and possible remote execution.

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2360-1 advisory.

  - Open vSwitch (aka openvswitch) 2.11.0 through 2.15.0 has a use-after-free in decode_NXAST_RAW_ENCAP     (called from ofpact_decode and ofpacts_decode) during the decoding of a RAW_ENCAP action. (CVE-2021-36980)

  - In ovs versions v0.90.0 through v2.5.0 are vulnerable to heap buffer over-read in flow.c. An unsafe     comparison of minimasks function could lead access to an unmapped region of memory. This vulnerability     is capable of crashing the software, memory modification, and possible remote execution. (CVE-2022-32166)

  - An out-of-bounds read in Organization Specific TLV was found in various versions of OpenvSwitch.
    (CVE-2022-4337)

  - An integer underflow in Organization Specific TLV was found in various versions of OpenvSwitch.
    (CVE-2022-4338)
