DLA-1953-1 clamav -- LTS security update
- Date Reported:
- 10 Oct 2019
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 34359.
In Mitre's CVE dictionary: CVE-2019-12625, CVE-2019-12900.
- More information:
It was discovered that clamav, the open source antivirus engine, is affected by the following security vulnerabilities:
Denial of Service (DoS) vulnerability, resulting from excessively long scan times caused by non-recursive zip bombs. Among others, this issue was mitigated by introducing a scan time limit.
Out-of-bounds write in ClamAV's NSIS bzip2 library when attempting decompression in cases where the number of selectors exceeded the max limit set by the library.
This update triggers a transition from libclamav7 to libclamav9. As a result, several other packages will be recompiled against the fixed package after the release of this update: dansguardian, havp, python-pyclamav, c-icap-modules.
For Debian 8
Jessie, these problems have been fixed in version 0.101.4+dfsg-0+deb8u1.
We recommend that you upgrade your clamav packages.
