In Perl before 5.38.2, S_parse_uniprop_string in regcomp.c can write to unallocated space because a property name associated with a \p{...} regular expression construct is mishandled. The earliest affected version is 5.30.0.

An update of the perl package has been released.

According to the versions of the perl packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A vulnerability was found in perl. This issue occurs when a crafted regular expression is compiled by     perl, which can allow an attacker controlled byte buffer overflow in a heap allocated buffer.
    (CVE-2023-47038)

  - In Perl before 5.38.2, S_parse_uniprop_string in regcomp.c can write to unallocated space because a     property name associated with a \p{...} regular expression construct is mishandled. The earliest affected     version is 5.30.0. (CVE-2023-47100)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-448 advisory.

    2024-02-01: CVE-2023-47100 was added to this advisory.

    A crafted regular expression when compiled by perl 5.30.0 through 5.38.0 can cause a one-byte attacker     controlled buffer overflow in a heap allocated buffer. (CVE-2023-47038)

    In Perl before 5.38.2, S_parse_uniprop_string in regcomp.c can write to unallocated space because a     property name associated with a \p{...} regular expression construct is mishandled. The earliest affected     version is 5.30.0. (CVE-2023-47100)

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

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