raptor2

An integer underflow vulnerability exists in the raptor2 RDF Parser Toolkit used by Red Hat Enterprise Linux. This flaw occurs when normalizing a URI with the turtle parser, potentially leading to incorrect memory handling. Red Hat has released security updates addressing this issue in multiple versions of raptor2 for Red Hat Enterprise Linux 7 Extended Lifecycle Support and 9.4 Extended Update Support. The vulnerability is tracked as CVE-2024-57823 and is rated with high severity by Red Hat Product Security. No known exploits are reported in the wild at this time.

CVE-2024-57823 is an integer underflow vulnerability in the raptor2 component of the Redland RDF Parser Toolkit. The flaw occurs during URI normalization in the turtle parser, potentially leading to unexpected behavior or memory corruption. Red Hat has issued security advisories and updates for multiple Red Hat Enterprise Linux variants, including Extended Lifecycle Support 7 and Extended Update Support 9.2, to remediate this vulnerability. The advisories provide updated raptor2 packages that fix the integer underflow issue.

Red Hat Security Advisory: raptor2 security update

raptor

In Raptor RDF Syntax Library through 2.0.16, there is an integer underflow when normalizing a URI with the turtle parser in raptor_uri_normalize_path().

CVE-2024-57823 is a critical integer underflow vulnerability classified under CWE-191, found in the Raptor RDF Syntax Library (librdf) up to version 2.0.16. The vulnerability occurs in the raptor_uri_normalize_path() function, which is responsible for normalizing URIs when parsing Turtle syntax RDF data. During this normalization process, an integer underflow can happen if certain crafted URIs are processed, causing the internal length or index calculations to wrap around unexpectedly. This underflow can lead to buffer overflows or memory corruption, potentially allowing an attacker to execute arbitrary code, crash the application, or manipulate data integrity. The vulnerability has a CVSS v3.1 base score of 9.3, reflecting its critical nature with high impact on confidentiality, integrity, and availability. The attack vector is local (AV:L), but it requires no privileges (PR:N) or user interaction (UI:N), and the scope is changed (S:C), meaning the vulnerability can affect resources beyond the vulnerable component. Although no exploits are currently known in the wild, the vulnerability poses a significant risk to applications and services that utilize librdf for RDF data processing, especially those parsing untrusted input. The lack of available patches at the time of publication necessitates cautious handling of affected systems and monitoring for updates.
