リモートのRocky Linux 8ホストには、RLSA-2021:4251アドバイザリに記載されているとおり、複数の脆弱性の影響を受けるパッケージがインストールされています。

  - 2.3.0までの OpenJPEG の openmj2/pi.c の関数 pi_next_pcrl、pi_next_cprl、および pi_next_rpcl のゼロ除算の脆弱性により、リモートの攻撃者がサービス拒否 (アプリケーションクラッシュ) を引き起こす可能性があります。(CVE-2018-20845)

  - 2.3.0 までの OpenJPEG の openjp2/pi.c の関数 opj_get_encoding_parameters の p_tx0、p_tx1、p_ty0、および p_ty1 の不適切な計算により、整数オーバーフローが発生する可能性があります。(CVE-2018-20847)

  - OpenJPEG 2.3.0 では、opj_t1_encode_cblks 関数 (openjp2/t1.c) に整数オーバーフローの脆弱性があります。リモート攻撃者が、この脆弱性を悪用して、細工された bmp ファイルを介してサービス拒否を引き起こす可能性があります。(CVE-2018-5727)

  - OpenJPEG 2.3.0 で、opj_j2k_setup_encoder 関数 (openjp2/j2k.c) に領域外の左シフトによって整数オーバーフローが発生します。リモート攻撃者が、この脆弱性を悪用して、細工された bmp ファイルを介してサービス拒否を引き起こす可能性があります。(CVE-2018-5785)

  - バージョン2.4.0より前のOpenJPEGに欠陥が見つかりました。この欠陥により、攻撃者が特別に細工された入力を変換またはエンコーディング機能に提供し、領域外読み取りを引き起こす可能性があります。この脆弱性が最大の脅威となるのは、システムの可用性です。(CVE-2020-27843)

  - 2.4.0より前のバージョンのopenjpegのsrc/lib/openjp2/pi.c に欠陥が存在します。攻撃者がopenjpegの変換/エンコーディング機能に信頼できない入力を提供できる場合、領域外読み取りが発生する可能性があります。この欠陥による最大の影響は、アプリケーションの可用性にあります。（CVE-2020-27845）

  - OpenJPEG v2.4.0 の整数オーバーフローにより、リモートの攻撃者がアプリケーションをクラッシュさせ、サービス拒否 (DoS) を引き起こす可能性があります。これは、攻撃者が 1048576 ファイルを含むディレクトリでコマンドラインオプション -ImgDir を使用する場合に発生します。(CVE-2021-29338)

  - 細工された .j2k ファイルを展開するとき、sycc420_to_rgb の color.c:379:42 の openjpeg にヒープベースのバッファオーバーフローが見つかりました。攻撃者がこれを利用して openjpeg に対してコンパイルされたアプリの権限で任意のコードの実行する可能性があります。(CVE-2021-3575)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4686-1 advisory.

    It was discovered that Ghostscript incorrectly handled certain image files. If a user or automated system     were tricked into processing a specially crafted file, a remote attacker could use this issue to cause     Ghostscript to crash, resulting in a denial of service, or possibly execute arbitrary code.

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

According to the versions of the openjpeg2 package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in OpenJPEG's encoder. This flaw     allows an attacker to pass specially crafted x,y offset     input to OpenJPEG to use during encoding. The highest     threat from this vulnerability is to confidentiality,     integrity, as well as system     availability.(CVE-2020-27823)

  - A flaw was found in OpenJPEG's encoder in the     opj_dwt_calc_explicit_stepsizes() function. This flaw     allows an attacker who can supply crafted input to     decomposition levels to cause a buffer overflow. The     highest threat from this vulnerability is to system     availability.(CVE-2020-27824)

  - jp2/opj_decompress.c in OpenJPEG through 2.3.1 has a     use-after-free that can be triggered if there is a mix     of valid and invalid files in a directory operated on     by the decompressor. Triggering a double-free may also     be possible. This is related to calling     opj_image_destroy twice.(CVE-2020-15389)

  - A flaw was found in OpenJPEG in versions prior to     2.4.0. This flaw allows an attacker to provide     specially crafted input to the conversion or encoding     functionality, causing an out-of-bounds read. The     highest threat from this vulnerability is system     availability.(CVE-2020-27843)

  - A heap-buffer overflow was found in the way openjpeg2     handled certain PNG format files. An attacker could use     this flaw to cause an application crash or in some     cases execute arbitrary code with the permission of the     user running such an application.(CVE-2020-27814)

  - There's a flaw in openjpeg in versions prior to 2.4.0     in src/lib/openjp2/pi.c. When an attacker is able to     provide crafted input to be processed by the openjpeg     encoder, this could cause an out-of-bounds read. The     greatest impact from this flaw is to application     availability.(CVE-2020-27841)

  - There's a flaw in src/lib/openjp2/pi.c of openjpeg in     versions prior to 2.4.0. If an attacker is able to     provide untrusted input to openjpeg's     conversion/encoding functionality, they could cause an     out-of-bounds read. The highest impact of this flaw is     to application availability.(CVE-2020-27845)
