libaspell.a in GNU Aspell before 0.60.8 has a buffer over-read for a string ending with a single '\0' byte, if the encoding is set to ucs-2 or ucs-4 outside of the application, as demonstrated by the ASPELL_CONF environment variable.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - libaspell.a in GNU Aspell before 0.60.8 has a buffer over-read for a string ending with a single '\0'     byte, if the encoding is set to ucs-2 or ucs-4 outside of the application, as demonstrated by the     ASPELL_CONF environment variable. (CVE-2019-20433)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14289-1 advisory.

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP DirectoryIterator class accepts     filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security     vulnerabilities, e.g. in applications checking paths that the code is allowed to access. (CVE-2019-11045)

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP bcmath extension functions on some     systems, including Windows, can be tricked into reading beyond the allocated space by supplying it with     string containing characters that are identified as numeric by the OS but aren't ASCII numbers. This can     read to disclosure of the content of some memory locations. (CVE-2019-11046)

  - When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in     PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to supply it with data what     will cause it to read past the allocated buffer. This may lead to information disclosure or crash.
    (CVE-2019-11047, CVE-2019-11050)

  - libaspell.a in GNU Aspell before 0.60.8 has a buffer over-read for a string ending with a single '\0'     byte, if the encoding is set to ucs-2 or ucs-4 outside of the application, as demonstrated by the     ASPELL_CONF environment variable. (CVE-2019-20433)

  - When using fgetss() function to read data with stripping tags, in PHP versions 7.2.x below 7.2.27, 7.3.x     below 7.3.14 and 7.4.x below 7.4.2 it is possible to supply data that will cause this function to read     past the allocated buffer. This may lead to information disclosure or crash. (CVE-2020-7059)

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

This update for aspell fixes the following security issue :

CVE-2019-20433: Fixed a buffer over-read when processing strings ending with a single '\0' byte with ucs-2 and ucs-4 encoding (bsc#1161982).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
