The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.
mercurial: arbitrary command execution in mercurial repo with a git submodule (CVE-2017-17458)
mercurial: Buffer underflow in mpatch.c:mpatch_apply() (CVE-2018-13347)
Mercurial before 3.7.3 allows remote attackers to execute arbitrary code via a crafted name when converting a Git repository. (CVE-2016-3069)
The convert extension in Mercurial before 3.8 might allow context-dependent attackers to execute arbitrary code via a crafted git repository name. (CVE-2016-3105)
Mercurial prior to version 4.3 is vulnerable to a missing symlink check that can malicious repositories to modify files outside the repository (CVE-2017-1000115)
Mercurial prior to 4.3 did not adequately sanitize hostnames passed to ssh, leading to possible shell- injection attacks. (CVE-2017-1000116)
Mercurial version 4.5 and earlier contains a Incorrect Access Control (CWE-285) vulnerability in Protocol server that can result in Unauthorized data access. This attack appear to be exploitable via network connectivity. This vulnerability appears to have been fixed in 4.5.1. (CVE-2018-1000132)
The mpatch_apply function in mpatch.c in Mercurial before 4.6.1 incorrectly proceeds in cases where the fragment start is past the end of the original data, aka OVE-20180430-0004. (CVE-2018-13346)
Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
