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

  - 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)

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.

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)
