Description
A flaw was found in binutils. An attacker who is able to submit a crafted input file to be processed by the objdump program could cause a null pointer dereference. The greatest threat from this flaw is to application availability.
Statement
Red Hat has determined this vulnerability to be of low impact, as it can only be triggered by tricking the objdump program into disassembling a corrupt input file, which will only cause the program to fail.
binutils as shipped with Red Hat Enterprise Linux 8's GCC Toolset 10 and Red Hat Developer Toolset 10 are not affected by this flaw because the versions shipped have already received the patch.
