CVE-2020-6096 2 Fedoraproject, Gnu 2 Fedora, Glibc 2022-05-12 6.8 MEDIUM 8.1 HIGH
An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc 2.30.9000. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the 'num' parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows for program execution to continue in scenarios where a segmentation fault or crash should have occurred. The dangers occur in that subsequent execution and iterations of this code will be executed with this corrupted data.
CVE-2020-6098 1 Freediameter 1 Freediameter 2022-05-12 5.0 MEDIUM 7.5 HIGH
An exploitable denial of service vulnerability exists in the freeDiameter functionality of freeDiameter 1.3.2. A specially crafted Diameter request can trigger a memory corruption resulting in denial-of-service. An attacker can send a malicious packet to trigger this vulnerability.

An integer underflow issue exists in ntfs-3g 2017.3.23. A local attacker could potentially exploit this by running /bin/ntfs-3g with specially crafted arguments from a specially crafted directory to cause a heap buffer overflow, resulting in a crash or the ability to execute arbitrary code. In installations where /bin/ntfs-3g is a setuid-root binary, this could lead to a local escalation of privileges.
CVE-2021-37706 4 Asterisk, Debian, Sangoma and 1 more 4 Certified Asterisk, Debian Linux, Asterisk and 1 more 2022-04-25 9.3 HIGH 9.8 CRITICAL
PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In affected versions if the incoming STUN message contains an ERROR-CODE attribute, the header length is not checked before performing a subtraction operation, potentially resulting in an integer underflow scenario. This issue affects all users that use STUN. A malicious actor located within the victim’s network may forge and send a specially crafted UDP (STUN) message that could remotely execute arbitrary code on the victim’s machine. Users are advised to upgrade as soon as possible. There are no known workarounds.
CVE-2021-44489 2 Fisglobal, Yottadb 2 Gt.m, Yottadb 2022-04-22 5.0 MEDIUM 7.5 HIGH

CVE-2018-3999 1 Atlantiswordprocessor 1 Atlantis Word Processor 2022-04-19 6.8 MEDIUM 7.8 HIGH
An exploitable stack-based buffer overflow vulnerability exists in the JPEG parser of Atlantis Word Processor, version A specially crafted image embedded within a document can cause a length to be miscalculated and underflow. This length is then treated as unsigned and then used in a copying operation. Due to the length underflow, the application will then write outside the bounds of a stack buffer, resulting in a buffer overflow. An attacker must convince a victim to open a document in order to trigger this vulnerability.
CVE-2022-23034 2 Fedoraproject, Xen 2 Fedora, Xen 2022-04-19 2.1 LOW 5.5 MEDIUM
A PV guest could DoS Xen while unmapping a grant To address XSA-380, reference counting was introduced for grant mappings for the case where a PV guest would have the IOMMU enabled. PV guests can request two forms of mappings. When both are in use for any individual mapping, unmapping of such a mapping can be requested in two steps. The reference count for such a mapping would then mistakenly be decremented twice. Underflow of the counters gets detected, resulting in the triggering of a hypervisor bug check.
