CVE-2021-3491 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2021-09-14 | 7.2 HIGH | 8.8 HIGH |
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. This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b ("io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers") (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced in ddf0322db79c ("io_uring: add IORING_OP_PROVIDE_BUFFERS") (v5.7-rc1). | |||||
CVE-2021-3489 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2021-09-14 | 7.2 HIGH | 7.8 HIGH |
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. This issue was fixed via commit 4b81ccebaeee ("bpf, ringbuf: Deny reserve of buffers larger than ringbuf") (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced via 457f44363a88 ("bpf: Implement BPF ring buffer and verifier support for it") (v5.8-rc1). | |||||

CVE-2019-20421 | 3 Canonical, Debian, Exiv2 | 3 Ubuntu Linux, Debian Linux, Exiv2 | 2021-09-14 | 7.8 HIGH | 7.5 HIGH |
In Jp2Image::readMetadata() in jp2image.cpp in Exiv2 0.27.2, an input file can result in an infinite loop and hang, with high CPU consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file. | |||||

CVE-2019-20444 | 5 Canonical, Debian, Fedoraproject and 2 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2021-09-14 | 6.4 MEDIUM | 9.1 CRITICAL |
HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks a colon, which might be interpreted as a separate header with an incorrect syntax, or might be interpreted as an "invalid fold." | |||||
CVE-2020-11937 | 1 Canonical | 2 Ubuntu Linux, Whoopsie | 2021-09-13 | 2.1 LOW | 5.5 MEDIUM |
In whoopsie, parse_report() from whoopsie.c allows a local attacker to cause a denial of service via a crafted file. The DoS is caused by resource exhaustion due to a memory leak. Fixed in 0.2.52.5ubuntu0.5, 0.2.62ubuntu0.5 and 0.2.69ubuntu0.1. | |||||
CVE-2020-15707 | 8 Canonical, Debian, Gnu and 5 more | 15 Ubuntu Linux, Debian Linux, Grub2 and 12 more | 2021-09-13 | 4.4 MEDIUM | 6.4 MEDIUM |
Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions. | |||||
CVE-2019-7305 | 3 Canonical, Debian, Extplorer | 3 Ubuntu Linux, Debian Linux, Extplorer | 2021-09-13 | 7.5 HIGH | 9.8 CRITICAL |
Information Exposure vulnerability in eXtplorer makes the /usr/ and /etc/extplorer/ system directories world-accessible over HTTP. Introduced in the Makefile patch file debian/patches/debian-changes-2.1.0b6+dfsg-1 or debian/patches/adds-a-makefile.patch, this can lead to data leakage, information disclosure and potentially remote code execution on the web server. This issue affects all versions of eXtplorer in Ubuntu and Debian | |||||

In Apache HTTP Server 2.4.0-2.4.39, a limited cross-site scripting issue was reported affecting the mod_proxy error page. An attacker could cause the link on the error page to be malformed and instead point to a page of their choice. This would only be exploitable where a server was set up with proxying enabled but was misconfigured in such a way that the Proxy Error page was displayed. | |||||

CVE-2020-3341 | 4 Canonical, Cisco, Debian and 1 more | 4 Ubuntu Linux, Clam Antivirus, Debian Linux and 1 more | 2021-08-06 | 5.0 MEDIUM | 7.5 HIGH |
A vulnerability in the PDF archive parsing module in Clam AntiVirus (ClamAV) Software versions 0.101 - 0.102.2 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a stack buffer overflow read. An attacker could exploit this vulnerability by sending a crafted PDF file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process crash, resulting in a denial of service condition. |
