 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3983-1 [email protected] https://www.debian.org/lts/security/ Lucas Kanashiro December 04, 2024 https://wiki.debian.org/LTS

 Package : clamav Version : 1.0.7+dfsg-1~deb11u1 CVE ID : CVE-2024-20505 CVE-2024-20506 Debian Bug : #1080962

 Two vulnerabilities were found in ClamAV, an antivirus toolkit for Unix.

 CVE-2024-20505

 Affected versions could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to an out of bounds read. An attacker could exploit this vulnerability by submitting a crafted PDF file to be scanned by ClamAV on an affected device. An exploit could allow the attacker to terminate the scanning process.

 CVE-2024-20506

 Affected versions could allow an authenticated, local attacker to corrupt critical system files. The vulnerability is due to allowing the ClamD process to write to its log file while privileged without checking if the logfile has been replaced with a symbolic link. An attacker could exploit this vulnerability if they replace the ClamD log file with a symlink to a critical system file and then find a way to restart the ClamD process. An exploit could allow the attacker to corrupt a critical system file by appending ClamD log messages after restart.

 ClamAV was updated to version 1.0.7+dfsg-1~deb10u1. Due to the library soname bump, the reverse dependencies of libclamav9 were rebuilt against libclamav11.
 The following source packages were updated:

 - - c-icap-modules/1:0.5.4-2+deb11u1
 - - cyrus-imapd/3.2.6-2+deb11u3
 - - havp/0.93-2+deb11u1
 - - pg-snakeoil/1.3-2+deb11u1
 - - libclamunrar/1.0.3-1~deb11u1

 For Debian 11 bullseye, these problems have been fixed in version 1.0.7+dfsg-1~deb11u1.

 We recommend that you upgrade your clamav packages.
