"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:1071 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2023-34872:
    A vulnerability in Outline.cc for Poppler prior to 23.06.0 allows a remote attacker to cause a Denial of
    Service (DoS) (crash) via a crafted PDF file in OutlineItem::open.

    CVE-2022-38784:
    Poppler prior to and including 22.08.0 contains an integer overflow in the JBIG2 decoder
    (JBIG2Stream::readTextRegionSeg() in JBIGStream.cc). Processing a specially crafted PDF file or JBIG2
    image could lead to a crash or the execution of arbitrary code. This is similar to the vulnerability
    described by CVE-2022-38171 in Xpdf.

    CVE-2022-38171:
    Xpdf prior to version 4.04 contains an integer overflow in the JBIG2 decoder
    (JBIG2Stream::readTextRegionSeg() in JBIG2Stream.cc). Processing a specially crafted PDF file or JBIG2
    image could lead to a crash or the execution of arbitrary code. This is similar to the vulnerability
    described by CVE-2021-30860 (Apple CoreGraphics).

    CVE-2022-38349:
    An issue was discovered in Poppler 22.08.0. There is a reachable assertion in Object.h, will lead to
    denial of service because PDFDoc::replacePageDict in PDFDoc.cc lacks a stream check before saving an
    embedded file.

    CVE-2021-30860:
    An integer overflow was addressed with improved input validation. This issue is fixed in Security Update
    2021-005 Catalina, iOS 14.8 and iPadOS 14.8, macOS Big Sur 11.6, watchOS 7.6.2. Processing a maliciously
    crafted PDF may lead to arbitrary code execution. Apple is aware of a report that this issue may have been
    actively exploited.
