A flaw was found in GNU Binutils 2.35.1, where there is a heap-based buffer overflow in _bfd_elf_slurp_secondary_reloc_section in elf.c due to the number of symbols not calculated correctly. The highest threat from this vulnerability is to system availability.
CVE-2021-20291 3 Fedoraproject, Redhat, Storage Project 5 Fedora, Enterprise Linux, Openshift and 2 more 2024-08-03 6.5 Medium
A deadlock vulnerability was found in 'github.com/containers/storage' in versions before 1.28.1. When a container image is processed, each layer is unpacked using `tar`. If one of those layers is not a valid `tar` archive this causes an error leading to an unexpected situation where the code indefinitely waits for the tar unpacked stream, which never finishes. An attacker could use this vulnerability to craft a malicious image, which when downloaded and stored by an application using containers/storage, would then cause a deadlock leading to a Denial of Service (DoS).
CVE-2021-20264 2 Oracle, Redhat 2 Openjdk, Openjdk 2024-08-03 7.8 High
An insecure modification flaw in the /etc/passwd file was found in the openjdk-1.8 and openjdk-11 containers.
