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.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7985-1 advisory.

    Shin Ando discovered that the Xpdf toolkit embedded in TeX Live incorrectly handled memory when decoding     certain data streams. An attacker could possibly use this issue to cause TeX Live to crash, resulting in a     denial of service, or execute arbitrary code. This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04     LTS. (CVE-2022-24106, CVE-2022-24107)

    It was discovered that TeX Live allowed documents to make arbitrary network requests. If a user or     automated system were tricked into opening a specially crafted document, a remote attacker could possibly     use this issue to exfiltrate sensitive information, or perform other network-related attacks. This issue     only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2023-32668)

    It was discovered that TeX Live incorrectly handled certain TrueType fonts. If a user or automated system     were tricked into opening a specially crafted TrueType font, a remote attacker could use this issue to     cause TeX Live to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue     only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2024-25262)

Tenable has extracted the preceding description block directly from the Ubuntu 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

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

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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 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)

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)
