Description
A vulnerability classified as problematic has been found in GNU Binutils 2.43. Affected is the function xstrdup of the file xstrdup.c of the component ld. The manipulation leads to memory leak. It is possible to launch the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue.
