**Name of the Vulnerable Software and Affected Versions**
libyang versions prior to 5.2.15
**Description**
The `lyb read string()` function in `src/parser lyb.c` contains an integer overflow. This occurs when parsing a maliciously crafted LYB binary blob, leading to a heap buffer overflow. An attacker capable of supplying LYB data to a libyang consumer, such as a NETCONF server or sysrepo, can cause a crash or heap corruption.
