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).

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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-2022-38171)

Note that Nessus relies on the presence of the package as reported by the vendor.

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.

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

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

The remote host is affected by the vulnerability described in GLSA-202405-18 (Xpdf: Multiple Vulnerabilities)

  - In Xpdf 4.02, SplashOutputDev::endType3Char(GfxState *state) SplashOutputDev.cc:3079 is trying to use the     freed `t3GlyphStack->cache`, which causes an `heap-use-after-free` problem. The codes of a previous fix     for nested Type 3 characters wasn't correctly handling the case where a Type 3 char referred to another     char in the same Type 3 font. (CVE-2020-25725)

  - Xpdf 4.02 allows stack consumption because of an incorrect subroutine reference in a Type 1C font     charstring, related to the FoFiType1C::getOp() function. (CVE-2020-35376)

  - There is a Null Pointer Dereference vulnerability in the XFAScanner::scanNode() function in XFAScanner.cc     in xpdf 4.03. (CVE-2021-27548)

  - In Xpdf prior to 4.04, the DCT (JPEG) decoder was incorrectly allowing the 'interleaved' flag to be     changed after the first scan of the image, leading to an unknown integer-related vulnerability in     Stream.cc. (CVE-2022-24106)

  - Xpdf prior to 4.04 lacked an integer overflow check in JPXStream.cc. (CVE-2022-24107)

  - xpdf 4.03 has heap buffer overflow in the function readXRefTable located in XRef.cc. An attacker can     exploit this bug to cause a Denial of Service (Segmentation fault) or other unspecified effects by sending     a crafted PDF file to the pdftoppm binary. (CVE-2022-27135)

  - 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-2022-38171)

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