Important: gfs2-utils

Issue Overview: A stack overflow vulnerability was found in gfs2-utils. The hash table traversal code in metawalk.c uses alloca with an exponentially-derived size from the untrusted on-disk didepth field without bounds validation. A crafted GFS2 filesystem image with a large didepth value causes...

Important: aspell

Issue Overview: A flaw was found in Aspell. An attacker could achieve arbitrary code execution or cause a Denial of Service DoS by convincing a user to process a specially crafted dictionary file. This issue occurs due to an integer calculation error during buffer capacity checks in the read-only...

Important: cyrus-sasl

Issue Overview: A heap-based buffer overflow flaw was found in Cyrus SASL. The addtochallenge function in the DIGEST-MD5 plugin computes the size of the buffer needed for a challenge/response field before DIGEST-MD5 quoting is applied, but does not recompute that size when quoting escaping specia...

Important: ghostscript

Issue Overview: A flaw was found in Ghostscript. When Ghostscript renders a crafted PostScript or EPS document, it can bypass the -dSAFER sandbox and execute arbitrary shell commands in the context of the Ghostscript process. The issue chains memory corruption in document parsing with disabling o...

Medium: alsa-lib

Issue Overview: alsa-lib through 1.2.16.1 contains a stack buffer overflow in the sndctlasciielemidparse function that writes one byte past a 64-byte buffer when parsing a name= field with 64 or more characters. Attackers can supply a long control-element identifier string through saved state fil...

Medium: iperf3

Issue Overview: iperf3 3.20-3.21 esnet/iperf has a pre-auth heap buffer overflow in decryptrsamessage: a 256-byte RSA buffer is BIOread with the attacker-controlled ciphertext length guard warns only, so an unauthenticated client overflows the heap via an oversized authtoken; CVE-2026-101283...
