O problema está relacionado a falhas de segurança de memória, que podem levar à corrupção de memória. Com esforço suficiente, essas falhas poderiam ser exploradas para executar código arbitrário, permitindo que um invasor remoto acesse dados confidenciais, comprometa sua integridade e cause uma negação de serviço.

The issue is related to multiple unspecified vulnerabilities in the browser engine, which can cause a denial of service due to memory corruption and application crash, or possibly allow the execution of arbitrary code via unknown vectors.

The issue is caused by a buffer overflow in the graphite2::TtfUtil::CmapSubtable12Lookup function, located in TtfUtil.cpp, which is part of the Graphite 2 rendering tool used in Mozilla Firefox and Firefox ESR. This can be exploited by a remote attacker using a specially crafted Graphite smart font, potentially leading to a denial of service or other unspecified impacts.

The issue is caused by a buffer overflow in the graphite2::Slot::getAttr function in Graphite 2, which can be exploited by a remote attacker using a specially crafted Graphite smart font. This can lead to a denial of service or potentially other impacts.

The issue is related to a heap-based buffer overflow in the `graphite2::Slot::setAttr` function. This can be exploited by remote attackers using a crafted Graphite smart font, potentially leading to a denial of service or other unspecified impacts.

The issue is related to a buffer over-read in the graphite2::GlyphCache::Loader::Loader function, which can be exploited by remote attackers using a crafted Graphite smart font. This can cause a denial of service or possibly have other unspecified impacts.

The issue is related to the graphite2::TtfUtil::CmapSubtable12Lookup function in Graphite 2, which can be exploited by remote attackers using a crafted Graphite smart font. This can cause a denial of service due to a buffer over-read or possibly have other unspecified impacts.

The issue is related to a heap-based buffer overflow in the `graphite2::vm::Machine::Code::Code` function. This can be exploited by remote attackers using a crafted Graphite smart font, potentially leading to a denial of service or other unspecified impacts.

The issue is related to the graphite2::TtfUtil::CmapSubtable4NextCodepoint function in Graphite 2, which can be exploited by remote attackers using a crafted Graphite smart font. This can cause a denial of service due to a buffer over-read or possibly have other unspecified impacts.

The issue is related to a buffer over-read in the graphite2::Slot::getAttr function, which can be exploited by remote attackers using a crafted Graphite smart font. This can cause a denial of service or possibly have other unspecified impacts.

The issue is caused by a buffer overflow in the graphite2::GlyphCache::glyph function of Graphite 2, which is used in Mozilla Firefox and Firefox ESR. This can be exploited by a remote attacker using a specially crafted Graphite smart font, potentially leading to a denial of service or other unspecified impacts.

The graphite2::TtfUtil::GetTableInfo function in Graphite 2 does not initialize memory for an unspecified data structure, allowing remote attackers to cause a denial of service or possibly have unknown other impact via a crafted Graphite smart font.

The issue is related to the graphite2::FileFace::get table fn function in Graphite 2, which does not initialize memory for an unspecified data structure. This allows remote attackers to cause a denial of service or possibly have unknown other impact via a crafted Graphite smart font.

The issue is related to the graphite2::TtfUtil::CmapSubtable12NextCodepoint function in Graphite 2, which can be exploited by remote attackers using a crafted Graphite smart font. This can cause a denial of service due to a buffer over-read or possibly have other unspecified impacts.

The issue is caused by a buffer overflow in the CachedCmap.cpp component of Graphite 2, a rendering tool used in Mozilla Firefox and Firefox ESR. This can be exploited by a remote attacker using a specially crafted Graphite smart font, potentially leading to a denial of service or other unspecified impacts.

The issue is related to the `sec asn1d parse leaf` function, which improperly restricts access to a data structure. This can be exploited by remote attackers using crafted OCTET STRING data, potentially leading to a denial of service or execution of arbitrary code. The problem is described as a "use-after-poison" issue and is also related to a buffer overflow.

A race condition exists in the nsThreadManager::RegisterCurrentThread function, allowing remote attackers to execute arbitrary code or cause a denial of service. This is due to improper Media Decoder Thread creation at the time of a shutdown, resulting in use-after-free and heap memory corruption.

The issue allows remote attackers to execute arbitrary code via crafted use of JavaScript code for ordered list elements. This is due to a problem in the nsGfxScrollFrameInner::IsLTR function.
