The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3389-1 advisory.

    A vulnerability was discovered in GD Graphics Library (aka libgd), as used in PHP that does not zero     colorMap arrays before use. A specially crafted GIF image could use the uninitialized tables to read bytes     from the top of the stack.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

According to its banner, the version of PHP running on the remote web server is 7.1.x prior to 7.1.7. It is, therefore, affected by the following vulnerabilities :

  - An out-of-bounds read error exists in the GD Graphics     Library (LibGD) in the gdImageCreateFromGifCtx()     function within file gd_gif_in.c when handling a     specially crafted GIF file. An unauthenticated, remote     attacker can exploit this to disclose sensitive memory     contents or crash a process linked to the library.
    (CVE-2017-7890)

  - An out-of-bounds read error exists in Oniguruma in the     match_at() function within file regexec.c. An     unauthenticated, remote attacker can exploit this to     disclose sensitive memory contents or crash a process     linked to the library. (CVE-2017-9224)

  - An out-of-bounds write error exists in Oniguruma in the     next_state_val() function during regular expression     compilation. An unauthenticated, remote attacker can     exploit this to execute arbitrary code. (CVE-2017-9226)

  - An out-of-bounds read error exists in Oniguruma in the     mbc_enc_len() function within file utf8.c. An     unauthenticated, remote attacker can exploit this to     disclose memory contents or crash a process linked to     the library. (CVE-2017-9227)

  - An out-of-bounds write error exists in Oniguruma in the     bitset_set_range() function during regular expression     compilation. An unauthenticated, remote attacker can     exploit this to execute arbitrary code. (CVE-2017-9228)

  - An invalid pointer deference flaw exists in Oniguruma     in the left_adjust_char_head() function within file     regexec.c during regular expression compilation. An     unauthenticated, remote attacker can exploit this to     crash a process linked to the library, resulting in a     denial of service condition. (CVE-2017-9229)

  - A flaw exists in OpenSSL in the EVP_SealInit() function     within file crypto/evp/p_seal.c due to returning an     undocumented value of '-1'. An unauthenticated, remote     attacker can exploit this to cause an unspecified     impact. (CVE-2017-11144)

  - An out-of-bounds read error exists in PHP in the     php_parse_date() function within file     ext/date/lib/parse_date.c. An unauthenticated, remote     attacker can exploit this to disclose memory contents or     cause a denial of service condition. (CVE-2017-11145)

  - A stack-based buffer overflow condition exists in PHP     in the msgfmt_parse_message() function due to improper     validation of user-supplied input when parsing locale.
    An unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-11362)

  - An off-by-one overflow condition exists in PHP in the     INI parsing API, specifically in the zend_ini_do_op()     function within file Zend/zend_ini_parser.c, due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-11628)

  - An out-of-bounds read error exists in PHP in the     finish_nested_data() function within file     ext/standard/var_unserializer.re. An unauthenticated,     remote attacker can exploit this to disclose memory     contents or cause a denial of service condition.
    (CVE-2017-12933)

  - A use-after-free error exists in PHP in the     zval_get_type() function within file     ext/standard/var_unserializer.c. An unauthenticated,     remote attacker can exploit this to execute arbitrary     code. (CVE-2017-12934)

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

This update was imported from the SUSE:SLE-12:Update update project.

This update for php53 fixes the several issues. These security issues were fixed :

  - CVE-2017-12933: The finish_nested_data function in     ext/standard/var_unserializer.re was prone to a buffer     over-read while unserializing untrusted data.
    Exploitation of this issue could have had an unspecified     impact on the integrity of PHP (bsc#1054430).

  - CVE-2017-11628: Stack-based buffer overflow in the     zend_ini_do_op() function in Zend/zend_ini_parser.c     could have caused a denial of service or potentially     allowed executing code (bsc#1050726).

  - CVE-2017-7890: The GIF decoding function     gdImageCreateFromGifCtx in the GD Graphics Library did     not zero colorMap arrays use.

  - CVE-2017-11147: The PHAR archive handler could have been     used by attackers supplying malicious archive files to     crash the PHP interpreter or potentially disclose     information due to a buffer over-read in the     phar_parse_pharfile function (bsc#1048094).

  - CVE-2017-11144: The openssl extension PEM sealing code     did not check the return value of the OpenSSL sealing     function, which could have lead to a crash of the PHP     interpreter (bsc#1048096).

The remote Oracle Linux 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2018-0406 advisory.

    [5.4.16-43.1]
    - gd: fix buffer over-read into uninitialized memory CVE-2017-7890

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

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

  - The GIF decoding function gdImageCreateFromGifCtx in gd_gif_in.c in the GD Graphics Library (aka libgd),     as used in PHP before 5.6.31 and 7.x before 7.1.7, does not zero colorMap arrays before use. A specially     crafted GIF image could use the uninitialized tables to read ~700 bytes from the top of the stack,     potentially disclosing sensitive information. (CVE-2017-7890)

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