Description

An issue was discovered in libxml2 before 2.10.4. When hashing empty dict strings in a crafted XML document, xmlDictComputeFastKey in dict.c can produce non-deterministic values, leading to various logic and memory errors, such as a double free. This behavior occurs because there is an attempt to use the first byte of an empty string, and any value is possible (not solely the '\0' value).

Solution(s)

  • huawei-euleros-2_0_sp11-upgrade-libxml2
  • huawei-euleros-2_0_sp11-upgrade-python3-libxml2
