A denial of service via regular expression in the py.path.svnwc component of py (aka python-py) through 1.9.0 could be used by attackers to cause a compute-time denial of service attack by supplying malicious input to the blame functionality.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - python-py: ReDoS in the py.path.svnwc component via mailicious input to blame functionality     (CVE-2020-29651)

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

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2022:2831-1 advisory.

  - A denial of service via regular expression in the py.path.svnwc component of py (aka python-py) through     1.9.0 could be used by attackers to cause a compute-time denial of service attack by supplying malicious     input to the blame functionality. (CVE-2020-29651)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5138-1 advisory.

    The py.path.svnwc component of py (aka python-py) through v1.9.0 contains

    a regular expression with an ambiguous subpattern that is susceptible to

    catastrophic backtracing. This could be used by attackers to cause a compute-time

    denial of service attack by supplying malicious input to the blame functionality.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

This update for python-py fixes the following issues :

  - CVE-2020-29651: Fixed regular expression denial of     service in svnwc.py (bsc#1179805, bsc#1184505).

This update was imported from the SUSE:SLE-15-SP1:Update update project.

#### 1.10.0 (2020-12-12) ####

  - Fix a regular expression DoS vulnerability in the     py.path.svnwc SVN blame functionality (CVE-2020-29651)

  - Update vendored apipkg: 1.4 => 1.5

  - Update vendored iniconfig: 1.0.0 => 1.1.1

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

#### 1.10.0 (2020-12-12) ####

  - Fix a regular expression DoS vulnerability in the     py.path.svnwc SVN blame functionality (CVE-2020-29651)

  - Update vendored apipkg: 1.4 => 1.5

  - Update vendored iniconfig: 1.0.0 => 1.1.1

#### 1.9.0 (2020-06-24) ####

  - Add type annotation stubs for the following modules :

  - ``py.error``

  - ``py.iniconfig``

  - ``py.path`` (not including SVN paths)

  - ``py.io``

  - ``py.xml``

    There are no plans to type other modules at this time.

    The type annotations are provided in external .pyi     files, not inline in the code, and may therefore contain     small errors or omissions. If you use ``py`` in     conjunction with a type checker, and encounter any type     errors you believe should be accepted, please report it     in an issue.
