At Entergy (NYSE: ETR), we power life. More than 100 years ago, our founder Harvey Couch started this company with a handshake, some sawdust and a vision. Couch wanted to bring safe, affordable, reliable energy to the Middle South – energy that would power the lives of people and communities. Today, we own and operate one of the cleanest large-scale U.S. power generating fleets including more than five gigawatts of carbon-free nuclear capacity, a fleet of highly efficient gas resources, and a fast-growing portfolio of renewable resources. The nearly 12,000 men and women of Entergy deliver electricity and gas services to 3 million utility customers in Arkansas, Louisiana, Mississippi and Texas, generating annual GAAP revenues of $13.8 billion. Headquartered in New Orleans, we continue to play a driving role in the economic growth of the Gulf South. Our work matters. That’s been true for more than 100 years. And as we look to the next century, we remember the constant that bridges our past and future: We Power Life. Fast Facts: Entergy currently has a 90% rating on the 2022 Corporate Equality Index released by the Human Rights Campaign Foundation.

Description

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, there is a heap-buffer-overflow (HBO) in icAnsiToUtf8() in the XML conversion path. The issue is triggered by a crafted ICC profile which causes icAnsiToUtf8(std::string&, char const*) to treat an input buffer as a C-string and call operations that rely on strlen()/null-termination. AddressSanitizer reports an out-of-bounds READ of size 115 past a 114-byte heap allocation, with the failure observed while running the iccToXml tool. This issue has been patched in version 2.3.1.6.

Description

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, there is a stack-buffer-overflow (SBO) in CIccTagFixedNum<>::GetValues() and a related bug chain. The primary crash is an AddressSanitizer-reported WRITE of size 4 that overflows a 4-byte stack variable (rv) via the call chain CIccTagFixedNum::GetValues() -> CIccTagStruct::GetElemNumberValue(). This issue has been patched in version 2.3.1.6.
