    self-referential might be fooled by encoded newlines
    and redirect instead to an an unexpected URL within the
    request URL.(CVE-2020-1927)

  - In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp

    malicious FTP server.(CVE-2020-1934)

  - A vulnerability was found in Apache HTTP Server 2.4.17

    request handling could be made to access freed memory
    in string comparison when determining the method of a

"According to the versions of the httpd packages installed, the

affected by the following vulnerabilities :

  - In Apache HTTP server 2.4.0 to 2.4.39, Redirects
    configured with mod_rewrite that were intended to be
    self-referential might be fooled by encoded newlines
    and redirect instead to an unexpected URL within the
    request URL.(CVE-2019-10098)

  - An invalid memory address dereference was discovered in
    dwfl_segment_report_module.c in libdwfl in elfutils
    through v0.174. The vulnerability allows attackers to
    cause a denial of service (application crash) with a
    crafted ELF file, as demonstrated by
    consider_notes.(CVE-2019-10092)

  - Type74 ED before 4.0 misuses 128-bit ECB encryption for
    small files, which makes it easier for attackers to
    obtain plaintext data via differential cryptanalysis of
    a file with an original length smaller than 128
    bits.(CVE-2020-1934)

  - In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp
    may use uninitialized memory when proxying to a
    malicious FTP server.(CVE-2020-1927)
