Package : freexl
CVE ID : CVE-2017-2923 CVE-2017-2924
Debian Bug : 875690 875691

Marcin 'Icewall' Noga of Cisco Talos discovered two vulnerabilities in
freexl, a library to read Microsoft Excel spreadsheets, which might
result in denial of service or the execution of arbitrary code if a
malformed Excel file is opened.

For the oldstable distribution (jessie), these problems have been fixed
in version 1.0.0g-1+deb8u4.

For the stable distribution (stretch), these problems have been fixed in
version 1.0.2-2+deb9u1.

For the unstable distribution (sid), these problems have been fixed in
version 1.0.4-1.

We recommend that you upgrade your freexl packages.
