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

  - A flaw was found in jasper before 2.0.25. An out of
    bounds read issue was found in jp2_decode function whic
    may lead to disclosure of information or program
    crash.(CVE-2021-26926)

  - The dec_clnpass function in libjasper/jpc/jpc_t1dec.c
    in JasPer 1.900.27 allows remote attackers to cause a
    denial of service (invalid memory write and crash) or
    possibly have unspecified other impact via a crafted
    image.(CVE-2017-5503)

  - The jpc_undo_roi function in libjasper/jpc/jpc_dec.c in
    JasPer 1.900.27 allows remote attackers to cause a
    denial of service (invalid memory read and crash) via a
    crafted image.(CVE-2017-5504)

  - The jas_matrix_asl function in jas_seq.c in JasPer
    1.900.27 allows remote attackers to cause a denial of
    service (invalid memory read and crash) via a crafted
    image.(CVE-2017-5505)

  - A NULL pointer dereference flaw was found in the way
    Jasper versions before 2.0.27 handled component
    references in the JP2 image format decoder. A specially
    crafted JP2 image file could cause an application using
    the Jasper library to crash when opened.(CVE-2021-3443)

  - A NULL pointer dereference flaw was found in the way
    Jasper versions before 2.0.26 handled component
    references in CDEF box in the JP2 image format decoder.
    A specially crafted JP2 image file could cause an
    application using the Jasper library to crash when
    opened.(CVE-2021-3467)
