Denial of service in ClamAV's DMG file format parser allows a remote, unauthenticated attacker to crash the scanning engine by submitting a crafted Apple Disk Image (DMG) for inspection. The flaw stems from an integer overflow triggered during boundary checks on DMG content and manifests only on 32-bit builds of ClamAV; memory corruption raises the theoretical possibility of expanded impact beyond a crash, though only DoS is described. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV.

Denial of service in ClamAV's ALZ archive parser allows an unauthenticated, remote attacker to crash the scanning engine by submitting a crafted ALZ file, with the vendor noting possible expanded impact beyond DoS. The flaw is a heap out-of-bounds write triggered during scanning, and because ClamAV is commonly deployed as an automated mail/upload gateway scanner, an attacker only needs to get a malicious file scanned. No public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV.

Availability-impacting out-of-bounds write in ClamAV's PESpin file-format parser lets an unauthenticated remote attacker crash the scanning engine by submitting a crafted PESpin-packed file for scanning. Because ClamAV frequently sits inline on mail gateways, file-upload paths, and proxies, a single malicious sample can terminate the scanning process and produce a denial of service; the memory corruption may permit expanded impact beyond DoS though only crash impact is confirmed. There is no public exploit identified at time of analysis and it is not on CISA KEV, with EPSS not provided.

Denial of service in ClamAV's InstallShield file format parser allows a remote, unauthenticated attacker (per CVSS PR:N) to crash the scanning engine and temporarily exhaust system resources by submitting a specially crafted InstallShield file for scanning. The flaw stems from improper handling of temporary resources during file scanning (CWE-770), impacting availability only (C:N/I:N/A:H) with no code execution or data exposure. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the network attack vector and low complexity make it easy to trigger anywhere ClamAV automatically scans attacker-supplied files.

A vulnerability in Universal Disk Format (UDF) processing of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
