CVE-2025-5054 1 Canonical 2 Apport, Ubuntu Linux 2025-08-22 N/A 4.7 MEDIUM
Race condition in Canonical apport up to and including 2.32.0 allows a local attacker to leak sensitive information via PID-reuse by leveraging namespaces. When handling a crash, the function `_check_global_pid_and_forward`, which detects if the crashing process resided in a container, was being called before `consistency_checks`, which attempts to detect if the crashing process had been replaced. Because of this, if a process crashed and was quickly replaced with a containerized one, apport could be made to forward the core dump to the container, potentially leaking sensitive information. `consistency_checks` is now being called before `_check_global_pid_and_forward`. Additionally, given that the PID-reuse race condition cannot be reliably detected from userspace alone, crashes are only forwarded to containers if the kernel provided a pidfd, or if the crashing process was unprivileged (i.e., if dump mode == 1).

CVE-2018-6540 2 Canonical, Gdraheim 2 Ubuntu Linux, Zziplib 2025-07-10 4.3 MEDIUM 6.5 MEDIUM
In ZZIPlib 0.13.67, there is a bus error caused by loading of a misaligned address in the zzip_disk_findfirst function of zzip/mmapped.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.
CVE-2018-6869 3 Canonical, Debian, Gdraheim 3 Ubuntu Linux, Debian Linux, Zziplib 2025-07-10 4.3 MEDIUM 6.5 MEDIUM
In ZZIPlib 0.13.68, there is an uncontrolled memory allocation and a crash in the __zzip_parse_root_directory function of zzip/zip.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.
CVE-2018-7725 3 Canonical, Gdraheim, Redhat 5 Ubuntu Linux, Zziplib, Enterprise Linux Desktop and 2 more 2025-07-10 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in ZZIPlib 0.13.68. An invalid memory address dereference was discovered in zzip_disk_fread in mmapped.c. The vulnerability causes an application crash, which leads to denial of service.
CVE-2018-6484 2 Canonical, Gdraheim 2 Ubuntu Linux, Zziplib 2025-07-10 4.3 MEDIUM 6.5 MEDIUM
In ZZIPlib 0.13.67, there is a memory alignment error and bus error in the __zzip_fetch_disk_trailer function of zzip/zip.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.

A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount.
