7 security issues in forky high

There are 7 open security issues in forky.

7 important issues:

CVE-2026-20213: A vulnerability in the PE file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition, or possibly other expanded impacts, resulting from memory corruption on an affected device. This vulnerability is due to improper boundary checks for content in PE files during scanning, which may result in an out-of-bounds buffer write. An attacker could exploit this vulnerability by submitting a crafted file that contains PE content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.
CVE-2026-20214: A vulnerability in the FSG file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition, or possibly other expanded impacts, resulting from memory corruption on an affected device. This vulnerability is due to improper boundary checks for content in FSG files during scanning, which may result in an out-of-bounds buffer write. An attacker could exploit this vulnerability by submitting a crafted file that contains portable executable content compressed with FSG to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.
CVE-2026-20215: A vulnerability in the 7z file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition, or possibly other expanded impacts, resulting from memory corruption on an affected device. This vulnerability is due to improper boundary checks for content in 7z files during scanning, which may result in an out-of-bounds buffer write. An attacker could exploit this vulnerability by submitting a crafted file that contains 7z content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.
CVE-2026-20216: A vulnerability in the InstallShield file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition on an affected device. This vulnerability is due to improper handling of temporary resources during file scanning. An attacker could exploit this vulnerability by submitting a crafted InstallShield file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to terminate the ClamAV scanning process and temporarily consume available system resources, resulting in a DoS condition on the affected software.
CVE-2026-20217: A vulnerability in the PESpin file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition, or possibly other expanded impacts, resulting from memory corruption on an affected device. This vulnerability is due to improper boundary checks for content in PESpin files during scanning, which may result in an out-of-bounds buffer write. An attacker could exploit this vulnerability by submitting a crafted file that contains PESpin content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.
CVE-2026-20243: A vulnerability in the ALZ file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition, or possibly other expanded impacts, resulting from memory corruption on an affected device. This vulnerability is due to improper boundary checks for content in ALZ files during scanning, which may result in an out-of-bounds buffer write. An attacker could exploit this vulnerability by submitting a crafted file that contains ALZ content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.
CVE-2026-20244: A vulnerability in the DMG file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition, or possibly other expanded impacts, resulting from memory corruption on an affected device. This vulnerability is due to improper boundary checks for content in DMG files during scanning, which may result in an integer overflow on 32-bit platforms only. An attacker could exploit this vulnerability by submitting a crafted file that contains DMG content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.

1 issue postponed or untriaged:

CVE-2026-20031: (postponed; to be fixed through a stable update) A vulnerability in the HTML Cascading Style Sheets (CSS) module of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper error handling when splitting UTF-8 strings. An attacker could exploit this vulnerability by submitting a crafted HTML file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to terminate the scanning process.

- ∙ ∙ Missing build on loong64
- ∙ ∙ Missing build on ppc64el
- ∙ ∙ Missing build on riscv64
- ∙ ∙ Autopkgtest deferred on armhf: missing arch:armhf build
- ∙ ∙ Autopkgtest deferred on loong64: missing arch:loong64 build
- ∙ ∙ Autopkgtest deferred on ppc64el: missing arch:ppc64el build
- ∙ ∙ Autopkgtest deferred on riscv64: missing arch:riscv64 build
- ∙ ∙ Autopkgtest for clamav/1.4.5+dfsg-2: amd64: Pass, arm64: Pass, i386: Pass, s390x: Pass
- ∙ ∙ Autopkgtest for cyrus-imapd/3.12.2-1: amd64: Pass, arm64: Test triggered (failure will be ignored), i386: Failed (not a regression) ♻ (reference ♻), s390x: Pass
- ∙ ∙ Lintian check waiting for test results on armhf, ppc64el, loong64, riscv64 - info
- ∙ ∙ Reproducibility check deferred on armhf: missing builds - info
- ∙ ∙ Too young, only 1 of 5 days old
- Additional info (not blocking):
- ∙ ∙ Piuparts tested OK - https://piuparts.debian.org/sid/source/c/clamav.html
