Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3815-1 advisory.

- An issue was discovered in ezXML 0.8.3 through 0.8.6. The function ezxml_decode, while parsing a crafted XML file, performs incorrect memory handling, leading to a heap-based buffer over-read while running strchr() starting with a pointer after a '\0' character (where the processing of a string was finished).
(CVE-2019-20005)

- An issue was discovered in ezXML 0.8.3 through 0.8.6. The function ezxml_char_content puts a pointer to the internal address of a larger block as xml->txt. This is later deallocated (using free), leading to a segmentation fault. (CVE-2019-20006)

- An issue was discovered in ezXML 0.8.2 through 0.8.6. The function ezxml_str2utf8, while parsing a crafted XML file, performs zero-length reallocation in ezxml.c, leading to returning a NULL pointer (in some compilers). After this, the function ezxml_parse_str does not check whether the s variable is not NULL in ezxml.c, leading to a NULL pointer dereference and crash (segmentation fault). (CVE-2019-20007)

- An issue was discovered in ezXML 0.8.3 through 0.8.6. The function ezxml_ent_ok() mishandles recursion, leading to stack consumption for a crafted XML file. (CVE-2019-20198)

- An issue was discovered in ezXML 0.8.3 through 0.8.6. The function ezxml_decode, while parsing a crafted XML file, performs incorrect memory handling, leading to NULL pointer dereference while running strlen() on a NULL pointer. (CVE-2019-20199)

- An issue was discovered in ezXML 0.8.3 through 0.8.6. The function ezxml_decode, while parsing crafted a XML file, performs incorrect memory handling, leading to a heap-based buffer over-read in the normalize line endings feature. (CVE-2019-20200)

- An issue was discovered in ezXML 0.8.3 through 0.8.6. The ezxml_parse_* functions mishandle XML entities, leading to an infinite loop in which memory allocations occur. (CVE-2019-20201)

- An issue was discovered in ezXML 0.8.3 through 0.8.6. The function ezxml_char_content() tries to use realloc on a block that was not allocated, leading to an invalid free and segmentation fault.
(CVE-2019-20202)

- The ezxml_toxml function in ezxml 0.8.6 and earlier is vulnerable to OOB write when opening XML file after exhausting the memory pool. (CVE-2021-26220)

- The ezxml_new function in ezXML 0.8.6 and earlier is vulnerable to OOB write when opening XML file after exhausting the memory pool. (CVE-2021-26221, CVE-2021-26222)

- An issue was discovered in libezxml.a in ezXML 0.8.6. The function ezxml_internal_dtd(), while parsing a crafted XML file, performs incorrect memory handling, leading to a NULL pointer dereference while running strcmp() on a NULL pointer. (CVE-2021-30485)

- An issue was discovered in libezxml.a in ezXML 0.8.6. The function ezxml_internal_dtd() performs incorrect memory handling while parsing crafted XML files, which leads to an out-of-bounds write of a one byte constant. (CVE-2021-31229)

- An issue was discovered in libezxml.a in ezXML 0.8.6. The function ezxml_parse_str() performs incorrect memory handling while parsing crafted XML files (writing outside a memory region created by mmap).
(CVE-2021-31347)

- An issue was discovered in libezxml.a in ezXML 0.8.6. The function ezxml_parse_str() performs incorrect memory handling while parsing crafted XML files (out-of-bounds read after a certain strcspn failure).
(CVE-2021-31348)

- An issue was discovered in libezxml.a in ezXML 0.8.6. The function ezxml_decode() performs incorrect memory handling while parsing crafted XML files, leading to a heap-based buffer overflow. (CVE-2021-31598)

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

Solution

Update the affected packages.
