The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2022:1263 advisory.
kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)
kernel: use-after-free in RDMA listen() (CVE-2021-4028)
kernel: fget: check that the fd still exists after getting a ref to it (CVE-2021-4083)
kernel: xfs: raw block device data leak in XFS_IOC_ALLOCSP IOCTL (CVE-2021-4155)
aide: heap-based buffer overflow on outputs larger than B64_BUF (CVE-2021-45417)
kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)
openssl: Infinite loop in BN_mod_sqrt() reachable when parsing certificates (CVE-2022-0778)
kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)
cyrus-sasl: failure to properly escape SQL input allows an attacker to execute arbitrary SQL commands (CVE-2022-24407)
xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks for whether a UTF-8 character is valid in a certain context. (CVE-2022-25235)
xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters into namespace URIs. (CVE-2022-25236)
In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
