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.

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 version of Apple iOS running on the mobile device is prior to 12.5.5. It is, therefore, affected by multiple vulnerabilities.

The version of Apple iOS running on the mobile device is prior to 14.8. It is, therefore, affected by multiple vulnerabilities.

The remote host is running a version of macOS / Mac OS X that is prior to Catalina Security Update 2021-005. It is, therefore, affected by multiple vulnerabilities, including the following:

  - Arbitrary code execution when processing a maliciously crafted image. (CVE-2021-30835, CVE-2021-30847)

  - An integer overflow issue due to insufficient input validation, which can lead to arbitrary code     execution by an unauthenticated attacker when processing a maliciously crafted PDF. (CVE-2021-30860)

  - Arbitrary code execution when processing a maliciously crafted dfont file. (CVE-2021-30841,     CVE-2021-30842, CVE-2021-30843)

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.

The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.6 Big Sur. It is, therefore, affected by multiple vulnerabilities including the following:

  - A use after free issue was addressed with improved memory management. Exploitation of this vulnerability may lead to     arbitrary code execution. (CVE-2021-30858)

  - An integer overflow was addressed with improved input validation. Exploitation of this vulnerability may lead to     arbitrary code execution. (CVE-2021-30860)
