CVE-2020-6796 – Mozilla: Missing bounds check on shared memory read in the parent process
https://notcve.org/view.php?id=CVE-2020-6796
A content process could have modified shared memory relating to crash reporting information, crash itself, and cause an out-of-bound write. This could have caused memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 73 and Firefox < ESR68.5. Un procesamiento de contenido podría haber modificado una memoria compartida relacionada con la información de los reportes de bloqueos de aplicación, el bloqueo en sí mismo, y causar una escritura fuera de límites. Esto podría haber causado una corrupción de memoria y un bloqueo potencialmente explotable. • https://bugzilla.mozilla.org/show_bug.cgi?id=1610426 https://security.gentoo.org/glsa/202003-02 https://usn.ubuntu.com/4278-2 https://www.mozilla.org/security/advisories/mfsa2020-05 https://www.mozilla.org/security/advisories/mfsa2020-06 https://access.redhat.com/security/cve/CVE-2020-6796 https://bugzilla.redhat.com/show_bug.cgi?id=1801916 • CWE-787: Out-of-bounds Write •
CVE-2020-6800 – Mozilla: Memory safety bugs fixed in Firefox 73 and Firefox ESR 68.5
https://notcve.org/view.php?id=CVE-2020-6800
Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR 68.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5. Los desarrolladores de Mozilla y los miembros de comunidad han reportado bugs de seguridad de la memoria presentes en Firefox versión 72 y Firefox ESR versión 68.4. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1595786%2C1596706%2C1598543%2C1604851%2C1608580%2C1608785%2C1605777 https://security.gentoo.org/glsa/202003-02 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4278-2 https://usn.ubuntu.com/4328-1 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2020-05 https://www.mozilla.org/security/advisories/mfsa2020-06 https://www.mozilla.org/security/advisories/mfsa2020-07 https://access.redhat.com • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
