CVE-2023-29469
An issue was discovered in libxml2 before 2.10.4.
MEDIUM 6.5EPSS 1.00%
Does this matter?
Lower severity and a low EPSS score (1.00%). Track it; it rarely justifies an emergency change on its own.
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).
