"The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by
multiple vulnerabilities as referenced in the SUSE-SU-2022:3802-1 advisory.

  - Out-of-bounds accesses in the functions pi_next_lrcp, pi_next_rlcp, pi_next_rpcl, pi_next_pcrl,
    pi_next_rpcl, and pi_next_cprl in openmj2/pi.c in OpenJPEG through 2.3.0 allow remote attackers to cause a
    denial of service (application crash). (CVE-2018-20846)

  - OpenJPEG before 2.3.1 has a heap buffer overflow in color_apply_icc_profile in bin/common/color.c.
    (CVE-2018-21010)

  - 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)

  - 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)

  - 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 openjpeg's t2 encoder in versions prior to 2.4.0. An attacker who is able to provide
    crafted input to be processed by openjpeg could cause a null pointer dereference. The highest impact of
    this flaw is to application availability. (CVE-2020-27842)

  - 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)

  - 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)

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