critical Nessus Plugin ID 195843

Synopsis

The remote Red Hat 6 host is affected by multiple vulnerabilities that will not be patched.

Description

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.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
