The _validaterepo function in sshpeer in Mercurial before 3.2.4 allows remote attackers to execute arbitrary commands via a crafted repository name in a clone command.

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 1.6.4 fails to verify the Common Name field of SSL certificates which allows remote     attackers who acquire a certificate signed by a Certificate Authority to perform a man-in-the-middle     attack. (CVE-2010-4237)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 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)

  - The _validaterepo function in sshpeer in Mercurial before 3.2.4 allows remote attackers to execute     arbitrary commands via a crafted repository name in a clone command. (CVE-2014-9462)

  - 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)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

According to the versions of the mercurial package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The _validaterepo function in sshpeer in Mercurial before 3.2.4 allows remote attackers to execute     arbitrary commands via a crafted repository name in a clone command. (CVE-2014-9462)

  - 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)

  - The binary delta decoder in Mercurial before 3.7.3 allows remote attackers to execute arbitrary code via a     (1) clone, (2) push, or (3) pull command, related to (a) a list sizing rounding error and (b) short     records. (CVE-2016-3630)

  - The mpatch_decode function in mpatch.c in Mercurial before 4.6.1 mishandles certain situations where there     should be at least 12 bytes remaining after the current position in the patch data, but actually are not,     aka OVE-20180430-0001. (CVE-2018-13348)

The remote host is affected by the vulnerability described in GLSA-201612-19 (Mercurial: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mercurial. Please       review the CVE identifier and bug reports referenced for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process.
  Workaround :

    There is no known workaround at this time.

CVE-2014-9462

Jesse Hertz of Matasano Security discovered that Mercurial, a distributed version control system, is prone to a command injection vulnerability via a crafted repository name in a clone command.

CVE-2014-9390

is a security vulnerability that affects mercurial repositories in a case-insensitive filesystem (eg. VFAT or HFS+). It allows for remote code execution of a specially crafted repository. This is less severe for the average Debian installation as they are usually set up with case-sensitive filesystems.
