CVE-2023-29469
MEDIUM6.5EPSS 0.16%發布日:2023/4/24修改日:2026/4/28
描述
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).
受影響套件(2)
- Alpine/libxml2from 0, < 2.10.4-r0
- Debian/libxml2from 0, < 2.9.10+dfsg-6.7+deb11u4
