Detailed vulnerability description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper handling of Executable and Linkable Format (ELF) files by the read_srclines function, as defined in the dwarf_getsrclines.c source code file.
