**Name of the Vulnerable Software and Affected Versions** binutils version 2.22 **Description** The issue is related to multiple integer overflows in the ` objalloc alloc` function and `objalloc alloc` macro, which can be exploited by remote attackers to cause a denial of service (crash) through vectors related to the addition of `CHUNK HEADER SIZE` to the length. This triggers a heap-based buffer overflow. **Recommendations** For binutils version 2.22, consider applying a patch that fixes the integer overflows in the ` objalloc alloc` function and `objalloc alloc` macro to prevent heap-based buffer overflows.
