According to the versions of the freetype package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - The t42_parse_encoding function in type42/t42parse.c in     FreeType before 2.5.4 does not properly update the     current position for immediates-only mode, which allows     remote attackers to cause a denial of service (infinite     loop) via a Type42 font.(CVE-2014-9747)

  - FreeType before 2.6.2 has a heap-based buffer over-read     in tt_cmap14_validate in sfnt/ttcmap.c.(CVE-2015-9383)

  - FreeType before 2.6.1 has a buffer over-read in     skip_comment in psaux/psobjs.c because     ps_parser_skip_PS_token is mishandled in an     FT_New_Memory_Face operation.(CVE-2015-9382)

  - FreeType before 2.6.1 has a heap-based buffer over-read     in T1_Get_Private_Dict in     type1/t1parse.c.(CVE-2015-9381)

  - In FreeType before 2.6.1, a buffer over-read occurs in     type1/t1parse.c on function T1_Get_Private_Dict where     there is no check that the new values of cur and limit     are sensible before going to Again.(CVE-2015-9290)

  - The parse_encoding function in type1/t1load.c in     FreeType before 2.5.3 allows remote attackers to cause     a denial of service (infinite loop) via a 'broken     number-with-base' in a Postscript stream, as     demonstrated by 8#garbage.(CVE-2014-9745)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A buffer over-read in the t1-parser of freetype, a font engine, has been found and fixed by checking limits more sensible.

For Debian 8 'Jessie', this problem has been fixed in version 2.5.2-3+deb8u3.

We recommend that you upgrade your freetype packages.

透過檢查更合理的限制，已發現並修正在　freetype　的　t1-parser　(一種字型引擎) 中的緩衝區過度讀取。針對 Debian 8「Jessie」，此問題已在 2.5.2-3+deb8u3 版本中修正。建議您升級 freetype 套件。注意：Tenable Network Security 已直接從 DLA 安全性公告擷取前置描述區塊。Tenable 已盡量在不造成其他問題的前提下，嘗試自動清理並將其格式化。

フォントエンジンであるfreetypeのt1パーサーでバッファオーバーリードが見つかり、より妥当な範囲をチェックすることで修正されました。

Debian 8「Jessie」では、この問題はバージョン2.5.2-3+deb8u3で修正されました。

freetypeパッケージをアップグレードすることをお勧めします。

注: Tenable Network Securityは、前述の記述ブロックをDLAセキュリティアドバイザリから直接抽出しています。Tenableでは、新たな問題を持ち込まずに、できる限り自動的に整理して書式設定するようにしています。

字体引擎 freetype 的 t1 解析器中发现缓冲区过度读取，并已通过更合理地检查限制修复。对于 Debian 8“Jessie”，此问题已在 2.5.2-3~deb8u3 版本中修复。建议您升级 freetype 程序包。注意：Tenable Network Security 已直接从 DLA 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，尽可能进行自动整理和排版。

According to the versions of the freetype package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The FreeType engine is a free and portable font     rendering engine, developed to provide advanced font     support for a variety of platforms and environments.
    FreeType is a library which can open and manages font     files as well as efficiently load, hint and render     individual glyphs. FreeType is not a font server or a     complete text-rendering library. Security Fix(es):The     t42_parse_encoding function in type42/t42parse.c in     FreeType before 2.5.4 does not properly update the     current position for immediates-only mode, which allows     remote attackers to cause a denial of service (infinite     loop) via a Type42 font.(CVE-2014-9747)In Sudo before     1.8.28, an attacker with access to a Runas ALL sudoer     account can bypass certain policy blacklists and     session PAM modules, and can cause incorrect logging,     by invoking sudo with a crafted user ID. For example,     this allows bypass of !root configuration, and USER=     logging, for a 'sudo -u \#$((0xffffffff))'     command.(CVE-2015-9383)FreeType before 2.6.1 has a     buffer over-read in skip_comment in psaux/psobjs.c     because ps_parser_skip_PS_token is mishandled in an     FT_New_Memory_Face operation.(CVE-2015-9382)FreeType     before 2.6.1 has a heap-based buffer over-read in     T1_Get_Private_Dict in     type1/t1parse.c.(CVE-2015-9381)In FreeType before     2.6.1, a buffer over-read occurs in type1/t1parse.c on     function T1_Get_Private_Dict where there is no check     that the new values of cur and limit are sensible     before going to Again.(CVE-2015-9290)The parse_encoding     function in type1/t1load.c in FreeType before 2.5.3     allows remote attackers to cause a denial of service     (infinite loop) via a 'broken number-with-base' in a     Postscript stream, as demonstrated by     8#garbage.(CVE-2014-9745)The parse_charstrings function     in type1/t1load.c in FreeType 2 before 2.7 does not     ensure that a font contains a glyph name, which allows     remote attackers to cause a denial of service     (heap-based buffer over-read) or possibly have     unspecified other impact via a crafted     file.(CVE-2016-10244)
