Package        : freexl

CVE ID         : CVE-2017-2923 CVE-2017-2924
Debian Bug     : #875690 #875691


The Cisco Talos team reported two sensitive security issues affecting
FreeXL-1.0.3 and any previous version.

CVE-2017-2923

    An exploitable heap based buffer overflow vulnerability exists in
    the read_biff_next_record function of FreeXL 1.0.3. A specially
    crafted XLS file can cause a memory corruption resulting in remote
    code execution. An attacker can send malicious XLS file to trigger
    this vulnerability.

CVE-2017-2924

    An exploitable heap-based buffer overflow vulnerability exists in
    the read_legacy_biff function of FreeXL 1.0.3. A specially crafted
    XLS file can cause a memory corruption resulting in remote code
    execution. An attacker can send malicious XLS file to trigger this
    vulnerability.

For Debian 7 "Wheezy", these problems have been fixed in version
1.0.0b-1+deb7u4.

We recommend that you upgrade your freexl packages.
