glibc: denial of service

It was found that the files backend of Name Service Switch NSS did not isolate iteration over an entire database from key-based look-up API calls. An application performing look-ups on a database while iterating over it could enter an infinite loop, leading to a denial of service...

Scientific Linux Security Update : glibc on SL7.x x86_64 (20150305)

An out-of-bounds read flaw was found in the way glibc's iconv function converted certain encoded data to UTF-8. An attacker able to make an application call the iconv function with a specially crafted argument could use this flaw to crash that application. CVE-2014-6040 It was found that the file...

GNU glibc denial of service vulnerability (CNVD-2015-01962)

glibc is the libc library, or c runtime library, released by GNU. glibc is the lowest level api in the linux system, and almost any other runtime library will depend on glibc. Name Service Switch NSS's file backend fails to isolate the entire database iteration from key-based query API calls, and...
