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.

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.

It was discovered that Mercurial failed to properly check Git sub-repository URLs. A Mercurial repository that includes a Git sub-repository with a specially crafted URL could cause Mercurial to execute arbitrary code. (CVE-2016-3068)

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)

It was discovered that the Mercurial convert extension failed to sanitize special characters in Git repository names. A Git repository with a specially crafted name could cause Mercurial to execute arbitrary code when the Git repository was converted to a Mercurial repository. (CVE-2016-3069)

mercurial was updated to fix three security issues.

These security issues were fixed :

  - CVE-2016-3069: Arbitrary code execution when converting     Git repos (bsc#973176).

  - CVE-2016-3068: Arbitrary code execution with Git     subrepos (bsc#973177).

  - CVE-2016-3630: Remote code execution in binary delta     decoding (bsc#973175).

Security fix for CVE-2016-3630, CVE-2016-3068, CVE-2016-3069 and minor upgrade

Several vulnerabilities have been discovered in Mercurial, a distributed version control system. The Common Vulnerabilities and Exposures project identifies the following issues :

  - CVE-2016-3068     Blake Burkhart discovered that Mercurial allows URLs for     Git subrepositories that could result in arbitrary code     execution on clone.

  - CVE-2016-3069     Blake Burkhart discovered that Mercurial allows     arbitrary code execution when converting Git     repositories with specially crafted names.

  - CVE-2016-3630     It was discovered that Mercurial does not properly     perform bounds-checking in its binary delta decoder,     which may be exploitable for remote code execution via     clone, push or pull.

New mercurial packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, and -current to fix security issues.
