CVE-2021-21897 3 Debian, Fedoraproject, Ribbonsoft 4 Debian Linux, Extra Packages For Enterprise Linux, Fedora and 1 more 2022-10-28 6.8 MEDIUM 8.8 HIGH
A code execution vulnerability exists in the DL_Dxf::handleLWPolylineData functionality of Ribbonsoft dxflib 3.17.0. A specially-crafted .dxf file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2021-28701 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2022-10-28 4.4 MEDIUM 7.8 HIGH
Another race in XENMAPSPACE_grant_table handling Guests are permitted access to certain Xen-owned pages of memory. The majority of such pages remain allocated / associated with a guest for its entire lifetime. Grant table v2 status pages, however, are de-allocated when a guest switches (back) from v2 to v1. Freeing such pages requires that the hypervisor enforce that no parallel request can result in the addition of a mapping of such a page to a guest. That enforcement was missing, allowing guests to retain access to pages that were freed and perhaps re-used for other purposes. Unfortunately, when XSA-379 was being prepared, this similar issue was not noticed.
CVE-2021-41773 4 Apache, Fedoraproject, Netapp and 1 more 4 Http Server, Fedora, Cloud Backup and 1 more 2022-10-28 4.3 MEDIUM 7.5 HIGH
A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue is known to be exploited in the wild. This issue only affects Apache 2.4.49 and not earlier versions. The fix in Apache HTTP Server 2.4.50 was found to be incomplete, see CVE-2021-42013.
CVE-2021-3695 4 Fedoraproject, Gnu, Netapp and 1 more 14 Fedora, Grub, Ontap Select Deploy Administration Utility and 11 more 2022-10-28 4.4 MEDIUM 4.5 MEDIUM
A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12.
CVE-2021-41524 4 Apache, Fedoraproject, Netapp and 1 more 4 Http Server, Fedora, Cloud Backup and 1 more 2022-10-28 5.0 MEDIUM 7.5 HIGH
While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing, allowing an external source to DoS the server. This requires a specially crafted request. The vulnerability was recently introduced in version 2.4.49. No exploit is known to the project.
CVE-2021-28700 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2022-10-28 6.8 MEDIUM 4.9 MEDIUM
xen/arm: No memory limit for dom0less domUs The dom0less feature allows an administrator to create multiple unprivileged domains directly from Xen. Unfortunately, the memory limit from them is not set. This allow a domain to allocate memory beyond what an administrator originally configured.
CVE-2021-34798 8 Apache, Broadcom, Debian and 5 more 18 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 15 more 2022-10-28 5.0 MEDIUM 7.5 HIGH
Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier.
CVE-2021-39272 2 Fedoraproject, Fetchmail 2 Fedora, Fetchmail 2022-10-28 4.3 MEDIUM 5.9 MEDIUM
Fetchmail before 6.4.22 fails to enforce STARTTLS session encryption in some circumstances, such as a certain situation with IMAP and PREAUTH.
CVE-2021-36386 2 Fedoraproject, Fetchmail 2 Fedora, Fetchmail 2022-10-28 5.0 MEDIUM 7.5 HIGH
report_vbuild in report.c in Fetchmail before 6.4.20 sometimes omits initialization of the vsnprintf va_list argument, which might allow mail servers to cause a denial of service or possibly have unspecified other impact via long error messages. NOTE: it is unclear whether use of Fetchmail on any realistic platform results in an impact beyond an inconvenience to the client user.
CVE-2022-33068 2 Fedoraproject, Harfbuzz Project 2 Fedora, Harfbuzz 2022-10-28 4.3 MEDIUM 5.5 MEDIUM
An integer overflow in the component hb-ot-shape-fallback.cc of Harfbuzz v4.3.0 allows attackers to cause a Denial of Service (DoS) via unspecified vectors.
CVE-2021-33477 6 Debian, Eterm Project, Fedoraproject and 3 more 6 Debian Linux, Eterm, Fedora and 3 more 2022-10-28 6.5 MEDIUM 8.8 HIGH
rxvt-unicode 9.22, rxvt 2.7.10, mrxvt 0.5.4, and Eterm 0.9.7 allow (potentially remote) code execution because of improper handling of certain escape sequences (ESC G Q). A response is terminated by a newline.
CVE-2021-45931 2 Fedoraproject, Harfbuzz Project 2 Fedora, Harfbuzz 2022-10-28 4.3 MEDIUM 6.5 MEDIUM
HarfBuzz 2.9.0 has an out-of-bounds write in hb_bit_set_invertible_t::set (called from hb_sparseset_t<hb_bit_set_invertible_t>::set and hb_set_copy).
CVE-2022-27664 2 Fedoraproject, Golang 2 Fedora, Go 2022-10-28 N/A 7.5 HIGH
In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error.
