CVE-2021-27345 2 Debian, Long Range Zip Project 2 Debian Linux, Long Range Zip 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A null pointer dereference was discovered in ucompthread in stream.c in Irzip 0.631 which allows attackers to cause a denial of service (DOS) via a crafted compressed file.
CVE-2021-27291 3 Debian, Fedoraproject, Pygments 3 Debian Linux, Fedora, Pygments 2024-11-21 5.0 MEDIUM 7.5 HIGH
In pygments 1.1+, fixed in 2.7.4, the lexers used to parse programming languages rely heavily on regular expressions. Some of the regular expressions have exponential or cubic worst-case complexity and are vulnerable to ReDoS. By crafting malicious input, an attacker can cause a denial of service.
CVE-2021-27229 2 Debian, Mumble 2 Debian Linux, Mumble 2024-11-21 6.8 MEDIUM 8.8 HIGH
Mumble before 1.3.4 allows remote code execution if a victim navigates to a crafted URL on a server list and clicks on the Open Webpage text.
CVE-2021-27219 5 Broadcom, Debian, Fedoraproject and 2 more 7 Brocade Fabric Operating System Firmware, Debian Linux, Fedora and 4 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in GNOME GLib before 2.66.6 and 2.67.x before 2.67.3. The function g_bytes_new has an integer overflow on 64-bit platforms due to an implicit cast from 64 bits to 32 bits. The overflow could potentially lead to memory corruption.
CVE-2021-27218 5 Broadcom, Debian, Fedoraproject and 2 more 7 Brocade Fabric Operating System Firmware, Debian Linux, Fedora and 4 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in GNOME GLib before 2.66.7 and 2.67.x before 2.67.4. If g_byte_array_new_take() was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 2**32, causing unintended length truncation.
CVE-2021-27212 2 Debian, Openldap 2 Debian Linux, Openldap 2024-11-21 5.0 MEDIUM 7.5 HIGH
In OpenLDAP through 2.4.57 and 2.5.x through 2.5.1alpha, an assertion failure in slapd can occur in the issuerAndThisUpdateCheck function via a crafted packet, resulting in a denial of service (daemon exit) via a short timestamp. This is related to schema_init.c and checkTime.
CVE-2021-27135 3 Debian, Fedoraproject, Invisible-island 3 Debian Linux, Fedora, Xterm 2024-11-21 7.5 HIGH 9.8 CRITICAL
xterm before Patch #366 allows remote attackers to execute arbitrary code or cause a denial of service (segmentation fault) via a crafted UTF-8 combining character sequence.
CVE-2021-26937 3 Debian, Fedoraproject, Gnu 3 Debian Linux, Fedora, Screen 2024-11-21 7.5 HIGH 9.8 CRITICAL
encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character sequence.
CVE-2021-26933 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-11-21 2.1 LOW 5.5 MEDIUM
An issue was discovered in Xen 4.9 through 4.14.x. On Arm, a guest is allowed to control whether memory accesses are bypassing the cache. This means that Xen needs to ensure that all writes (such as the ones during scrubbing) have reached the memory before handing over the page to a guest. Unfortunately, the operation to clean the cache is happening before checking if the page was scrubbed. Therefore there is no guarantee when all the writes will reach the memory.
CVE-2021-26932 4 Debian, Fedoraproject, Linux and 1 more 9 Debian Linux, Fedora, Linux Kernel and 6 more 2024-11-21 1.9 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one is reported to the backend driver, and the backend driver then loops over the results, performing follow-up actions based on the success or failure of each operation. Unfortunately, when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively implying their success from the success of related batch elements. In other cases, errors resulting from one batch element lead to further batch elements not being inspected, and hence successful ones to not be possible to properly unmap upon error recovery. Only systems with Linux backends running in PV mode are vulnerable. Linux backends run in HVM / PVH modes are not vulnerable. This affects arch/*/xen/p2m.c and drivers/xen/gntdev.c.
CVE-2021-26931 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 1.9 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests (such as out of memory conditions), it isn't correct to assume a plain bug. Memory allocations potentially causing such crashes occur only when Linux is running in PV mode, though. This affects drivers/block/xen-blkback/blkback.c and drivers/xen/xen-scsiback.c.
CVE-2021-26930 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 4.6 MEDIUM 7.8 HIGH
An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service requests to the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be encountered. In one case, an error encountered earlier might be discarded by later processing, resulting in the caller assuming successful mapping, and hence subsequent operations trying to access space that wasn't mapped. In another case, internal state would be insufficiently updated, preventing safe recovery from the error. This affects drivers/block/xen-blkback/blkback.c.
CVE-2021-26929 2 Debian, Horde 2 Debian Linux, Groupware 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
An XSS issue was discovered in Horde Groupware Webmail Edition through 5.2.22 (where the Horde_Text_Filter library before 2.3.7 is used). The attacker can send a plain text e-mail message, with JavaScript encoded as a link or email that is mishandled by preProcess in Text2html.php, because bespoke use of \x00\x00\x00 and \x01\x01\x01 interferes with XSS defenses.
CVE-2021-26910 2 Debian, Firejail Project 2 Debian Linux, Firejail 2024-11-21 6.9 MEDIUM 7.8 HIGH
Firejail before 0.9.64.4 allows attackers to bypass intended access restrictions because there is a TOCTOU race condition between a stat operation and an OverlayFS mount operation.
CVE-2021-26720 2 Avahi, Debian 2 Avahi, Debian Linux 2024-11-21 4.6 MEDIUM 7.8 HIGH
avahi-daemon-check-dns.sh in the Debian avahi package through 0.8-4 is executed as root via /etc/network/if-up.d/avahi-daemon, and allows a local attacker to cause a denial of service or create arbitrary empty files via a symlink attack on files under /run/avahi-daemon. NOTE: this only affects the packaging for Debian GNU/Linux (used indirectly by SUSE), not the upstream Avahi product.
CVE-2021-26691 5 Apache, Debian, Fedoraproject and 2 more 8 Http Server, Debian Linux, Fedora and 5 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
In Apache HTTP Server versions 2.4.0 to 2.4.46 a specially crafted SessionHeader sent by an origin server could cause a heap overflow
CVE-2021-26690 4 Apache, Debian, Fedoraproject and 1 more 6 Http Server, Debian Linux, Fedora and 3 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Cookie header handled by mod_session can cause a NULL pointer dereference and crash, leading to a possible Denial Of Service
CVE-2021-26676 3 Debian, Intel, Opensuse 3 Debian Linux, Connman, Leap 2024-11-21 3.3 LOW 6.5 MEDIUM
gdhcp in ConnMan before 1.39 could be used by network-adjacent attackers to leak sensitive stack information, allowing further exploitation of bugs in gdhcp.
CVE-2021-26675 3 Debian, Intel, Opensuse 3 Debian Linux, Connman, Leap 2024-11-21 5.8 MEDIUM 8.8 HIGH
A stack-based buffer overflow in dnsproxy in ConnMan before 1.39 could be used by network adjacent attackers to execute code.
CVE-2021-26313 6 Amd, Arm, Broadcom and 3 more 11 Ryzen 5 5600x, Ryzen 7 2700x, Ryzen Threadripper 2990wx and 8 more 2024-11-21 2.1 LOW 5.5 MEDIUM
Potential speculative code store bypass in all supported CPU products, in conjunction with software vulnerabilities relating to speculative execution of overwritten instructions, may cause an incorrect speculation and could result in data leakage.
