According to the versions of the syslinux packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    The png_format_buffer function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x     before 1.4.8, and 1.5.x before 1.5.4 allows remote attackers to cause a denial of service (application     crash) via a crafted PNG image that triggers an out-of-bounds read during the copying of error-message     data.  NOTE: this vulnerability exists because of a CVE-2004-0421 regression. NOTE: this is called an off-     by-one error by some sources.(CVE-2011-2501)

    Buffer overflow in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before     1.5.4, when used by an application that calls the png_rgb_to_gray function but not the png_set_expand     function, allows remote attackers to overwrite memory with an arbitrary amount of data, and possibly have     unspecified other impact, via a crafted PNG image.(CVE-2011-2690)

    The png_err function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8,     and 1.5.x before 1.5.4 makes a function call using a NULL pointer argument instead of an empty-string     argument, which allows remote attackers to cause a denial of service (application crash) via a crafted PNG     image.(CVE-2011-2691)

    The png_handle_sCAL function in pngrutil.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x     before 1.4.8, and 1.5.x before 1.5.4 does not properly handle invalid sCAL chunks, which allows remote     attackers to cause a denial of service (memory corruption and application crash) or possibly have     unspecified other impact via a crafted PNG image that triggers the reading of uninitialized     memory.(CVE-2011-2692)

    Integer signedness error in the png_inflate function in pngrutil.c in libpng before 1.4.10beta01, as used     in Google Chrome before 17.0.963.83 and other products, allows remote attackers to cause a denial of     service (application crash) or possibly execute arbitrary code via a crafted PNG file, a different     vulnerability than CVE-2011-3026.(CVE-2011-3045)

    The png_set_text_2 function in pngset.c in libpng 1.0.x before 1.0.59, 1.2.x before 1.2.49, 1.4.x before     1.4.11, and 1.5.x before 1.5.10 allows remote attackers to cause a denial of service (crash) or execute     arbitrary code via a crafted text chunk in a PNG image file, which triggers a memory allocation failure     that is not properly handled, leading to a heap-based buffer overflow.(CVE-2011-3048)

    The png_push_read_zTXt function in pngpread.c in libpng 1.0.x before 1.0.58, 1.2.x before 1.2.48, 1.4.x     before 1.4.10, and 1.5.x before 1.5.10 allows remote attackers to cause a denial of service (out-of-bounds     read) via a large avail_in field value in a PNG image.(CVE-2012-3425)

    The png_convert_to_rfc1123 function in png.c in libpng 1.0.x before 1.0.64, 1.2.x before 1.2.54, and 1.4.x     before 1.4.17 allows remote attackers to obtain sensitive process memory information via crafted tIME     chunk data in an image file, which triggers an out-of-bounds read.(CVE-2015-7981)

    Multiple buffer overflows in the (1) png_set_PLTE and (2) png_get_PLTE functions in libpng before 1.0.64,     1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19     allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other     impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image.(CVE-2015-8126)

    Buffer overflow in the png_set_PLTE function in libpng before 1.0.65, 1.1.x and 1.2.x before 1.2.55,     1.3.x, 1.4.x before 1.4.18, 1.5.x before 1.5.25, and 1.6.x before 1.6.20 allows remote attackers to cause     a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth     value in an IHDR (aka image header) chunk in a PNG image.  NOTE: this vulnerability exists because of an     incomplete fix for CVE-2015-8126.(CVE-2015-8472)

    Integer underflow in the png_check_keyword function in pngwutil.c in libpng 0.90 through 0.99, 1.0.x     before 1.0.66, 1.1.x and 1.2.x before 1.2.56, 1.3.x and 1.4.x before 1.4.19, and 1.5.x before 1.5.26     allows remote attackers to have unspecified impact via a space character as a keyword in a PNG image,     which triggers an out-of-bounds read.(CVE-2015-8540)

    The png_set_text_2 function in libpng 0.71 before 1.0.67, 1.2.x before 1.2.57, 1.4.x before 1.4.20, 1.5.x     before 1.5.28, and 1.6.x before 1.6.27 allows context-dependent attackers to cause a NULL pointer     dereference vectors involving loading a text chunk into a png structure, removing the text, and then     adding another text chunk to the structure.(CVE-2016-10087)

    libpng before 1.6.32 does not properly check the length of chunks against the user limit.(CVE-2017-12652)

Tenable has extracted the preceding description block directly from the EulerOS syslinux security advisory.

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

已发现 libpng PNG 库中存在多个漏洞。通用漏洞和暴露计划识别以下问题：

- CVE-2015-8472 已发现 CVE-2015-8126 的原始补丁不完整，且未检测直接使用 png_set_PLTE 的应用程序可能造成的溢出。远程攻击者可利用此缺陷造成拒绝服务（应用程序崩溃）。

- CVE-2015-8540 Xiao Qixue 和 Chen Yu 发现 png_check_keyword 函数中有一个缺陷。远程攻击者可能利用此缺陷造成拒绝服务（应用程序崩溃）。

在 libpng10 的 png_check_keyword 中发现下溢读取问题。攻击者可能利用此缺陷，诱骗毫无防备的用户处理特别构建的 PNG 图像，从而造成越界读取。

请注意，Tenable Network Security 已直接从 Fedora 安全公告中提取上述描述块。Tenable 已尝试在不引入其他问题的情况下尽可能进行了自动整理和排版。

远程 Debian 主机上运行的 libpng 版本低于 1.2.44-1+squeeze6。因此，它受到以下漏洞的影响：

- 在解压缩 PNG 图像时，pngpread.c 文件中的 png_push_read_zTXt() 函数存在一个越界读取错误。未经认证的远程攻击者可利用此问题，通过大型“avail_in”字段造成拒绝服务。
 (CVE-2012-3425)

- 在处理小于 8 的小位深度值时，pngset.c 文件的 png_set_PLTE() 函数和 pngget.c 文件的 png_get_PLTE() 函数中存在缓冲区溢出。未经认证的远程攻击者可利用此漏洞，通过在 PNG 图像中特别构建的 IHDR 区块，造成拒绝服务或其他不明影响。(CVE-2015-8472)

- pngwutil.c 文件中的 png_check_keyword() 函数中存在整数下溢。未经认证的远程攻击者可利用此漏洞，通过特别构建的 PNG 图像（使用空格符作为关键词），造成拒绝服务或其他不明影响。(CVE-2015-8540)

远程主机上安装的 libpng 版本低于 1.5.13-8。因此，该应用程序受到 ALAS2-2023-1904 公告中提及的漏洞的影响。

  - 在 libpng 0.90 至 0.99 版本、1.0.x 至 1.0.66 版本、1.1.x 版本、1.2.x 至 1.2.56 版本、1.3.x 版本、1.4.x 至 1.4.19 版本以及 1.5.x 至 1.5.26 版本中，pngwutil.c 的 png_check_keyword 函数中存在整数下溢漏洞，该漏洞允许远程攻击者通过将空格字符用作 PNG 图像中的关键字来触发越界读取，从而造成不明影响。(CVE-2015-8540)

请注意，Nessus 尚未测试此问题，而是只依据应用程序自我报告的版本号进行判断。
