In Artifex MuPDF 1.12.0 and earlier, multiple memory leaks in the PDF parser allow an attacker to cause a denial of service (memory leak) via a crafted file.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7825-1 advisory.

    It was discovered that MuPDF incorrectly managed memory, resulting in a memory leak. An attacker could     possibly use this issue to cause a denial of service. This issue only affected Ubuntu 18.04 LTS.
    (CVE-2018-1000036)

    It was discovered that MuPDF could enter an infinite loop when parsing certain PDF files. An attacker     could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 18.04 LTS.
    (CVE-2018-10289)

    It was discovered that MuPDF incorrectly managed memory, possibly leading to a segmentation fault. An     attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 18.04     LTS. (CVE-2018-16647, CVE-2018-16648)

    It was discovered that MuPDF contained a use-after-free vulnerability. An attacker could possibly use this     issue to cause a denial of service. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.
    (CVE-2020-21896)

    It was discovered that MuPDF incorrectly managed memory, resulting in a memory leak. An attacker could     possibly use this issue to cause a denial of service or obtain sensitive information. This issue only     affected Ubuntu 20.04 LTS. (CVE-2020-26683)

    Maxim Mishechkin, Vitalii Akolzin, Shamil Kurmangaleev, Denis Straghkov, Fedor Nis'kov and Ivan Gulakov     discovered that MuPDF incorrectly managed memory under certain circumstances, leading to a double-free. An     attacker could possibly use this to cause a denial of service. This issue only affected Ubuntu 16.04 LTS,     Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2021-3407)

    Xuwei Liu discovered that MuPDF may perform an out-of-bounds write under certain circumstances. An     attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 18.04     LTS and Ubuntu 20.04 LTS. (CVE-2021-37220)

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2765 advisory.

    Multiple issues have been discovered in mupdf. CVE-2016-10246 Buffer overflow in the main function in     jstest_main.c allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted     file. CVE-2016-10247 Buffer overflow in the my_getline function in jstest_main.c allows remote attackers     to cause a denial of service (out-of-bounds write) via a crafted file. CVE-2017-6060 Stack-based buffer     overflow in jstest_main.c allows remote attackers to have unspecified impact via a crafted image.
    CVE-2018-10289 An infinite loop in the fz_skip_space function of the pdf/pdf-xref.c file. A remote     adversary could leverage this vulnerability to cause a denial of service via a crafted pdf file.
    CVE-2018-1000036 Multiple memory leaks in the PDF parser allow an attacker to cause a denial of service     (memory leak) via a crafted file. CVE-2020-19609 A heap based buffer over-write in tiff_expand_colormap()     function when parsing TIFF files allowing attackers to cause a denial of service. For Debian 9 stretch,     these problems have been fixed in version 1.14.0+ds1-4+deb9u1. We recommend that you upgrade your mupdf     packages.
