MGASA-2019-0162 - Updated clamav packages fix security vulnerabilities

Publication date: 12 May 2019
URL: https://advisories.mageia.org/MGASA-2019-0162.html
Type: security
Affected Mageia releases: 6
CVE: CVE-2019-1787,
     CVE-2019-1788,
     CVE-2019-1789

Description:
The updated packages fix security vulnerabilities:

A vulnerability in the Portable Document Format (PDF) scanning functionality
of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow
an unauthenticated, remote attacker to cause a denial of service (DoS)
condition on an affected device. The vulnerability is due to a lack of
proper data handling mechanisms within the device buffer while indexing
remaining file data on an affected device. An attacker could exploit this
vulnerability by sending crafted PDF files to an affected device. A
successful exploit could allow the attacker to cause a heap buffer
out-of-bounds read condition, resulting in a crash that could result in a
denial of service condition on an affected device. (CVE-2019-1787)

A vulnerability in the Object Linking & Embedding (OLE2) file scanning
functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior
could allow an unauthenticated, remote attacker to cause a denial of service
condition on an affected device. The vulnerability is due to a lack of
proper input and validation checking mechanisms for OLE2 files sent an
affected device. An attacker could exploit this vulnerability by sending
malformed OLE2 files to the device running an affected version ClamAV
Software. An exploit could allow the attacker to cause an out-of-bounds
write condition, resulting in a crash that could result in a denial of
service condition on an affected device. (CVE-2019-1788)

An out-of-bounds heap read condition when scanning PE files. (CVE-2019-1789)
