A sufficiently large value in the variable `sz` overflows with `sz+7` in and the negative value passes the maximum available memory buffer check. The root cause is an integer overflow in `setup_malloc`. A crafted file may trigger out of bounds write in `f->vendor = get8_packet(f) `. Stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. Since there is another integer overflow an attacker may overflow it too to force `setup_malloc` to return 0 and make the exploit more reliable. The root cause is a potential integer overflow in `sizeof(char*) * (f->comment_list_length)` which may make `setup_malloc` allocate less memory than required. A crafted file may trigger memory write past an allocated heap buffer in `start_decoder`. This affects NI System Configuration 2023 Q3 and all previous versions. Successful exploitation requires that an attacker can provide a specially crafted response. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.ĭelta Electronics' CNCSoft-B version 1.0.0.4 and DOPSoft versions 4.0.0.82 and prior are vulnerable to stack-based buffer overflow, which could allow an attacker to execute arbitrary code.īuffer Overflow vulnerability in XnView Classic v.2.51.5 allows a local attacker to execute arbitrary code via a crafted TIF file.Ī stack-based buffer overflow vulnerability exists in NI System Configuration that could result in information disclosure and/or arbitrary code execution. A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable.
