CVE-2009-3083 2 Pidgin, Redhat 3 Libpurple, Pidgin, Enterprise Linux 2026-04-23 N/A
The msn_slp_sip_recv function in libpurple/protocols/msn/slp.c in the MSN protocol plugin in libpurple in Pidgin before 2.6.2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an SLP invite message that lacks certain required fields, as demonstrated by a malformed message from a KMess client.
CVE-2007-3731 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-04-23 N/A
The Linux kernel 2.6.20 and 2.6.21 does not properly handle an invalid LDT segment selector in %cs (the xcs field) during ptrace single-step operations, which allows local users to cause a denial of service (NULL dereference and OOPS) via certain code that makes ptrace PTRACE_SETREGS and PTRACE_SINGLESTEP requests, related to the TRACE_IRQS_ON function, and possibly related to the arch_ptrace function.
CVE-2009-0793 3 Littlecms, Redhat, Sun 3 Lcms, Enterprise Linux, Openjdk 2026-04-23 N/A
cmsxform.c in LittleCMS (aka lcms or liblcms) 1.18, as used in OpenJDK and other products, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted image that triggers execution of incorrect code for "transformations of monochrome profiles."
CVE-2008-5006 1 University Of Washington 1 Imap Toolkit 2026-04-23 N/A
smtp.c in the c-client library in University of Washington IMAP Toolkit 2007b allows remote SMTP servers to cause a denial of service (NULL pointer dereference and application crash) by responding to the QUIT command with a close of the TCP connection instead of the expected 221 response code.
CVE-2007-0887 1 Gecad Technologies 1 Axigen Mail Server 2026-04-23 N/A
axigen 1.2.6 through 2.0.0b1 does not properly parse login credentials, which allows remote attackers to cause a denial of service (NULL dereference and application crash) via a base64-encoded "*\x00" sequence on the imap port (143/tcp).
