DATE | CVE | VULNERABILITY TITLE | RISK |
---|---|---|---|
2021-06-12 | CVE-2021-32555 | Link Following vulnerability in Canonical Ubuntu Linux It was discovered that read_file() in apport/hookutils.py would follow symbolic links or open FIFOs. | 2.1 |
2021-06-04 | CVE-2021-3489 | Out-of-bounds Write vulnerability in multiple products The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. | 7.2 |
2021-06-04 | CVE-2021-3490 | Out-of-bounds Write vulnerability in multiple products The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. | 7.2 |
2021-06-04 | CVE-2021-3491 | Out-of-bounds Write vulnerability in multiple products The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem. | 7.2 |
2021-04-26 | CVE-2020-15078 | Missing Authentication for Critical Function vulnerability in multiple products OpenVPN 2.5.1 and earlier versions allows a remote attackers to bypass authentication and access control channel data on servers configured with deferred authentication, which can be used to potentially trigger further information leaks. | 7.5 |
2020-12-26 | CVE-2020-29385 | Infinite Loop vulnerability in multiple products GNOME gdk-pixbuf (aka GdkPixbuf) before 2.42.2 allows a denial of service (infinite loop) in lzw.c in the function write_indexes. | 5.5 |
2020-12-09 | CVE-2020-27349 | Missing Authorization vulnerability in Canonical Ubuntu Linux Aptdaemon performed policykit checks after interacting with potentially untrusted files with elevated privileges. | 2.1 |
2020-12-09 | CVE-2020-16128 | Information Exposure Through an Error Message vulnerability in Canonical Ubuntu Linux The aptdaemon DBus interface disclosed file existence disclosure by setting Terminal/DebconfSocket properties, aka GHSL-2020-192 and GHSL-2020-196. | 2.1 |
2020-12-04 | CVE-2020-16123 | Race Condition vulnerability in Canonical Ubuntu Linux An Ubuntu-specific patch in PulseAudio created a race condition where the snap policy module would fail to identify a client connection from a snap as coming from a snap if SCM_CREDENTIALS were missing, allowing the snap to connect to PulseAudio without proper confinement. | 2.1 |
